Need advice from Griffith owners before I remove the headlamp "pod" from the fenders:

Does the existing 5" low beam headlamp itself have a removable lens, or is it a full glass assembly that the bulb just slips into?

I want to fit "projector" lamps into the existing lamp housings, but want to keep the existing "bucket" & beam adjusting base so I can adjust the beam pattern once the projectors are installed. I was hoping the lense is removable from the reflector so I could mount the projector assy onto the front of the reflector, but don't know if the the lense is removable from the reflector....

And don't want to pull the entire pods until I get info on if the lense is able to separate from the reflector.

Has anyone converted their existing headlamps to "projectors"? Advice and/or pictures?

I don’t know the exact answer to your question but if you go to the Powers TVR website you will see that their replacement unit seems to be reflector and lens combined....I.e., a unit.

Alex, thxs for the reply. Powers also shows the "reflector" as a separate part, so I'm assuming ( hoping?) that the lense and reflectors are separate parts. but Powers doesn't show a lense only as a separate part for purchase (seems odd to me ). I really don't want to get everything taken apart and find out that the lamp unit in the pod is "one piece" and that the lense might not be able to be separated from the reflector.

The existing Griff headlamp light beam output is quite poor on my car: from looking from the outside of the car the backside of the actual lense of the lamp unit looks slightly cloudy, but the reflector still appears pretty shiny.....

I was hoping that there would be some pics of a disassembled Griffith pod and lamp assembly on Pistonheads, but haven't yet seen one via search function....

If you check the model number of the light unit you should find the specs online somewhere saying if the lens is a separate unit to the reflector

The original Cibie units are definitely one piece units i.e. the reflector bonded to the glass lens. I have two spare units so could check them outside the car.

The main beam bulb clips in and the side light bulb is just a push fit.

My car is a 1996 500 but I believe all Griffith with 5" units were the same.

This is a Griffith dip beam headlamp unit, the reflector and lens appear to be well and truly bonded together.

Thxs, Mike! Sure looks like the lens & reflector are in fact one piece! That answers my question about it being a 2 piece lens & reflector or not for the dipped beam in the pod on the fenders. I guess I'll have to find another way to install "projector" dipped beams on my Griffith....

Does anyone know of a 2 piece (separate lense & reflector ) from another vehicle or motorcycle that would fit in the Griffith dip-beam 5" headlamp???

Way back there used to be kits for a twin headlight conversion under those headlight covers

These photos might help with info' that has already been submitted relating to cars in the UK.

Quad light conversion for top lamps under the acrylic cover.
Small opaque lights are the turn indicators with amber bulbs.(not original).
Lower lights - main beam.


Full on lights in a sprinkling of rain.

Hella now do LED versions of those 90mm units. One version has an indicator halo too so the indicator units could be deleted from the body (yes I know this would involve more work).

Do you have a link to the Hella units?

Not for me though as my car is too far past original and I like original, I just loved the colour.

Off topic I know, just could not resist so I've just uploaded a thumbnail fit image.redcard



cool

Personally I think the bottom originals look too big. The 90 mm will fit , buy two hoover junior drive belts and they take up the gap.
Once again are they road legal ?
For the indicators, glass whiskey tumblers, see my pic. Buy the clear orange illumination bulbs.
Whilst fiddling with lights, four tail lamps, five stop lamps.

Was the Faceache post.

Should be a link to the datasheet:

https://www.hella.com/powersports/assets/media_glo...

You can check with Hella as to the certification of the units.

Thxs for the Hella link and the reference to their 90mm series. I'm looking at their "classic LED" 90mm series as it looks relatively simple to install as long as you purchase the supporting installation parts from Hella (mounting plates, wiring adapters, adjuster screws etc ) which they seem to have listed in their technical brochures. Relatively expensive in total, but vastly superior light output and beam pattern: like a new car versus original old school lights. Hella makes USA/DOT/EU approved (LHD) versions as well as UK (RHD) versions. Their Tech manuals & product brochures are interesting & informative but seem difficult to find & navigate on their website; however I suspect they have consumer product/support lines to get phone info & support on retail vendors, etc....

Upgrading the Griff lighting looks like it will be a coming Fall/Winter project for my Griff...

Was your Griff first registered in the states or did you import it from elsewhere? smile

Hi Rob, My RHD Griff 500 pre-serp was previously registered in UK and then in Netherlands where headlamps were switched to LHD. I purchased the Griff 3 years ago in Netherlands and had it shipped to UK & left with my son in Nottingham who registered it and drove it occasionally while I waited for the Griff to turn "25". When it became 25 yrs old "to-the-month-of-manufacture", it became eligible for import into USA, so I had it shipped to USA Fall 2019. I'm guessing there might be something less than 10 or so Griffs ( if that... ) here in USA. Nobody here in the USA knows what it is as TVR never brought anything into the USA after the early Wedge cars.

RE "lighting": Although dipped lights were converted to LHD beam pattern, the lighting is poor and the need to move to more effective, modern lighting.

As you can imagine, I've lurked & looked daily - and still do daily - at Pistonheads TVR & Griff/Chim forums for years while looking for Griff 500's, tech advice, etc and am continually amazed at the level of knowledge and expertise that's wonderfully shared by TVR owners! Prior to shipping the Griff to USA, my son & I took the Griff for a few euro trips, Nurburgring driving, Fr/Gr/Sw etc, to enjoy the Griff with seat time with my son. I also had the Griff serviced a number of times by Joolz ( absolutely EXCELLENT! ) for tuning & upgrades while my son was driving it in the UK prior to it being shipped to me.

Stay safe...
