Aftermarket LED headlight upgrades?
Discussion
Hi,
Having recently driven on sections of the A46 between Lincoln and Newark at night, where the cats eyes have not been maintained, I found that visibility on dip beam was rather worse than I remembered and it was difficult to see where the road went. I have recently replaced the OEM bulbs with standard brightness equivalents, so not a consequence of 6 year old bulbs.
I do not believe much of the hype over 140% brighter bulbs as the tech spec still shows the output as 1450 Lumens plus/minus a small margin. I cannot see how one bulb can be significantly brighter if the official output is the same.
So, searching the web, I found http://www.horizonleds.co.uk/exterior-leds/cree-le... at 3500 lumens.
The question I guess is, the bulbs will physically fit OK. But where do I put the ballast box? Does it fit in the headlamp unit? How would I secure it?

RPM do a conversion for older 911's. Thread about it here together with some other options

I have ordered a set from Hong Kong - will post when they arrive... in 2 months!
Cool, I'll put in a calendar note for late March!Recently installed some Phillips WhiteVision halogens. Really good upgrade in brightness and whiteness, but if these LEDs are all they're cracked up to be, they should be a step-change.
Look forward to your update.
The LED bulbs arrived from Hong Kong yesterday - a little earlier than expected.
The bulbs have large heat sinks but there was no driver/ballast box.
Fitting was mostly easy with the exception that the heat sink prevented the retaining spring from being moved back into place. The solution was to unscrew the grub screw holding the spring in the headlamp unit, locate the spring into the bulb at approximately the right angle, put the bulb in the headlamp unit, locate the spring under the screw and tighten it down. Sounds worse than it was - took a few minutes.
Then the test drive on my closest unlit road - massive difference. The range is the same for the obvious reason that it is dictated by law in the alignment of the headlamp - but the area was completely lit with little/no fall-off in brightness so in reality you can see right up to the cutoff.
My only concern now regards longevity as the heat sink would imply a lot of heat to disperse, but the headlamp unit is hermetically sealed. I'll have to see what happens next.

Yes the heat issue is a killer with these bulbs for me. You'll not know if the fan fails and all that heat may not melt the headlamp plastic but it will seriously deteriorate all the glued components within. I've had an HID kit in mine for a year or so and its excellent - went for a 55w kit with 5000k bulbs and for me it looks completely stock next to a bi-xenon 987.
Cool. And just before I pull the trigger, it was these, right?

And your car is Gen 2?
Apologies for high maintenance!
