80W Cree Stop/Tailight bulbs

[ChimpOnGas]

I believe this new type is 'plug n play' and doesn't need the LED compatible flasher unit.

Stever will confirm, but he's already said he's using them on the rears with standard incandescent bulbs in the front.

Running the two technologies front and rear on the same car at the same time tells me there's no LED compatible flasher unit required with the LEDs he's using.

[Stever]

yes plug and play

I didn't need anything else and have no fast flash or failed bulb issues

[Sardonicus]

Just fit CANBUS friendly ones as these have a simulated resistance to stop corruption/errors on the BUS and thus odd electronics behavior etc of later vehicles these are getting easier to source nowadays as later vehicles 2000> are far more common than old school stuff, this way you dont get the rapid indicator flash (incorrect resistance) it dont matter for tail lights brake lights etc

Just to confirm the indicator bulbs used in the Chimaera are P21W, otherwise known as BA15, this type of bulb has parallel pins.

It seems from reading Stever's posts the Griffith uses the off-set pin type indicator bulb known as a PY21W.

I'll correct my links so people order the right P21W parallel pin bulbs for the Chimaera.

I can highly recommend the latest generation of LED H4s, you will need to adjust your headlights down a bit to avoid dazzling oncoming drivers but the latest versions of these LED H4s allow you to make an 'LED to reflector' adjustment without touching your actual headlight adjusters.

This latest LED to reflector adjustment system a better approach in my opinion, because with the adjustable LED H4s you're actually fine tuning the refractive angle between the chip and the reflector itself, rather than keeping it the same and crudely adjusting the whole reflector down which definitely achieves the desired anti-dazzle objective but also has the effect of pushing the light further down into the road so creating a more intense but smaller pool of light right in front of you on dip beam.

Dave could you give a bit more info on these?

I followed your original LED post with great interest, but decided I couldn't go down the same route of adjusting my reflectors, partially due to the reasons you gave but also because one of my adjusters is seized and would need replacing to do that.

If the is a new LED type with the adjustment available on the unit itself I would be very interested as this would apart to solve my problem - but I know nothing about the LED technologies nor new types etc.

Might you have any more info on the nature and method of adjustment available from these, and possibly any links to the relevant products, if you would be so kind?

Many thanks,

Dom

Thanks for providing this link. I don't post here much, but thought I should feed back on these. I used the Ali Express link to buy a pair for the rear. They arrived this morning - total cost was £15.76 for the pair, since I got a new customer discount of $4.

Fitted straight away - takes no more than 2 minutes, and they're really effective. A lot brighter than the standard bulbs and I've always liked the immediacy of an LED indicator, which these obviously give.

A good upgrade.

Have you bought two pairs of P21Ws? (front and back) or a a pair of P21W and a pair of PY21W. I was under the impression the front indicator bulbs on Griff and Chim were both PY21W.

[Matthew Poxon]

Scrap that comment above, I am confused. After a bit of reading it looks like the Griffith has the P21W bulb for rear indicators not the PY21W. Yet Stever's post says PY21W?

Is yours a late chim with the chieftain tank lights or the early one with the fiesta lights?

Hi Mathew, on my Chimaera I have the earlier the fiesta lights, in these lights you need the P21W (BA15) bulb type which has parallel pins.





My understanding is the Griffith uses the same bulb but with offset pins, this is known as a PY21W (BAU15S).




I have also sent you a little retarded proposal on Messenger mate

The later style Chimaera rear lights are also parallel pins.

Useful to know, thanks.

So we believe only the Grifters have wonky pins, which makes sense given what we already know about them

[Matthew Poxon]

I have just looked at a spare Cavalier unit I have in the loft (rear taillights for Griffith)

Looks like all are straight pins (BA15S / 382 / P21Y) expect the dual filament Tail / Fog unit which is offset (BAZ15D / 566)

I can also confirm that the chieftain tank indicator units that both the Chim and Griff share for the front indicator are also straight pins.

Good write up Dave.

I changed my stop and tail lights for LEDs and as mentioned the difference is night and day. Having done this it was pointed out to me that the rear indicators on my Griff were difficult to see because of the brightness of the other lamps so I changed my rears only to these

https://www.ebay.co.uk/itm/CANBUS-382-PY21W-12V-CO... and the difference is amazing again and there were no errors or flash issues literally plug and play.

See this quick video for results

https://www.youtube.com/watch?v=DxXgfBqO-Rw&fe...

Ok, so that makes the above link from Stever wrong then as it points to the PY21W type which is the offset pin type.

This seems odd as he's clearly fitted them to his Griff

Ok, I've just sussed it out, Stever's link points to what the eBay seller describes as a PY21W, but if you read his description he refers to the bulb in his listing as having opposite pins (Ie not offset pins). The thing is as we all know a PY21W has offset pins, so the eBay seller is the one who's confused, he's clearly listing a PY21W in the title of his description but further down the listing describing a opposite pin P21W which is also what he's sending.

The eBay seller needs to correct his listing title to P21W!

Stever was just lucky, if the bulbs he purchased from the eBay seller were genuinely PY21W as described in the listing title they would have had offset pins and they wouldn't have fitted his Griff indicators, because as we now know thanks to Mathew Poxton and others all the TVRs were discussing here (Chim & Griff) use the same opposite pin type P21W indicator bulb.

Only the fog and reverse lights use the offset pin type PY21W, because of the incorrect eBay listing I've ended up both types, I guess that means my offset pin PY21W type are going to be my new reverse and fog light bulbs, that still leaves me with two spare offset pin PY21W bulbs if anyone is interested in having them off me at what I paid so they can do the same?

When you understand a BA15s is the same thing as a P21W, this image makes it all very easy to understand, shame the feking eBayer Muppet didn't study it before creating his listing.....



In summary....

• A P21W (BA15s) has opposite pins and is used as an indicator bulb in all Griffs and Chims

• A PY21W (BAU15s) has offset pins and is only used in Griffs and Chims in the fog light or reversing light

[Matthew Poxon]

Well done for getting to the bottom of this mess! What a bloody nightmare.

Just one minor correction the Griff Tail / Fog is offset pin but also a dual filament bulb so is a BAZ15D / 566

When I swapped mine over for (hopefully) the correct bulbs I will do a mini write up for the Griff boys with all the correct bulb types and LED alternatives similar to what you have done in the past for the Chim.

Looking forward to receiving my indicator bulbs I could not believe the difference in Steve's video. Our cars are very small and low compared to modern vehicles, these bulbs will IMO represent an important safety improvement in being seen much earlier by other drivers..

Thanks to all that have contributed, great idea.

[Classic Chim]

I’m starting to get a bit nervous of blind stupid drivers up me chuff too. Brighter lights might keep them at a safe distance for starters.

Yeah welldone got getting to the bottom of this one

[ric355]

Having tried mine in the dark, I'm actually a bit concerned that they're too bright. They burn your eyes if you look straight at them...

Ok, thanks to Steve's impressive YouTube demo and his confirmation there are no nasty issues with these new type of LED indicator bulb, I've decided to complete the LED conversion on 'Ol Gasbag' by fitting them to the indicators too.

I chose to buy through Ali Express as you can get four of the exact same bulbs for just £32.49, I've purchased from Ali Express in the past and had no issues with the experience. While delivery usually takes three weeks because they're coming direct from China (where they're made), buying the bulbs this way does work out nearly half the price.

I'll be patient.... and take the saving

Many thanks to Stever for the original heads up, great result and well shared

Edited by ChimpOnGas on Wednesday 8th November 11:22

Ok boys, these arrived yesterday so just over two weeks to come direct from China, they look very good quality and the bulbs came extremely well packaged, they even came with a free set of LED side repeater bulbs which luckily are the correct 501 type for the Chimaera's side repeaters.

If you buy direct from China using Ali Express these LED indicator bulbs are £18.66 a pair vs £30 a pair if you buy them from the UK seller 'Car Mod Shop', I bought a set of four which cost me £32.49 vs the £60 I would have paid with 'Car Mod Shop' for the exact same thing, as far as I'm concerned that's an extremely worthwhile saving if you can wait the extra two weeks for delivery .

I'll fit them over the weekend after I've cleaned the car which is still filthy from last weekend's amazing but rather wet blast through some of the best driving roads in Wales, once installed I'll add a YouTube video link to this post so we can all see how they work on a Chimaera.

Here are the LED 501s that came free with my new LED indicator bulbs...



And the P21W (BA15) indicator bulbs themselves... with parallel pins!



Looking good

Dave.

I got the free gift too (I ordered from your link). I didn't realize they actually fit the repeaters. They're still on my desk here so will have to take a look!

[ChimpOnGas]

Not the best video, I always forget to hold the phone in landscape.

It was a cold start about an hour ago so excuse the haze, but I think it proved the point, with the smoked Chimaera light covers as they are these very bright indicator bulbs are a no-brainer safety mod, especially in the winter when the light get covered in filth.

So after the above test I put the second one in immediately and will fit the two fronts tomorrow, great find Stever , and now half price for TVR owners direct from China thanks to Aliexpress

PS: As Stever confirmed there are no rapid flashing issues with these LED bulbs, just fit and enjoy a safer TVR

[Matthew Poxon]

Great result! Thanks for the update. I shall eagerly await mine.
