Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Are there any LED headlamp bulbs that can replace the halogen bulbs in mk1 cars, such as my 99 C2? I couldn�t really find much on this topic, save for those folks replacing the entire headlight assembly. But I am just focused on the bulb itself. I have no complaints about the Halogens in my car, but my mechanic told me to look into LED bulbs since they are much brighter.

POST 2Original post

No affiliation and have not tried any. Expensive to put through a trial run - https://www.superbrightleds.com/cat/...ype,H7,1,4933:

POST 3Original post

Skip the LED bulbs. The technology isn't there yet. It's not much different than sticking HID bulbs in a halogen housing. It's not actually any additional light output, and it glares everywhere.

POST 4Original post

If you don't have projectors, i would NOT do anything...LED or HID. And, plus one with the captain, LED is not there yet as far as bulbs. Even the ones from the legit companies have big heat sinks that are hard to fit, not sure but also might throw codes. TRS makes a drop in LED projector now so that may be an option... requires un gluing the lense tho. I'm about to do an HID install, will write up when I have time. https://www.theretrofitsource.com/pr...rojectors.html

POST 5Original post

FWIW, there�s a set of gen 1 xenons in the parts marketplace if you wanna pony up for em. All things considered, probably the best route.

POST 6Original post

I did HIDs in my son's boxster and they are great. Piece of cake. There is some great info in the later part of this thread on what to buy and how to install. https://rennlist.com/forums/996-foru...t-posting.html

POST 7Original post

I just finished re-wiring the harness inside my 2000 996 C2. I wanted to add LED bulbs to replace my halogens. Fahren Termitor H7�s look great. But was it worth the trouble? The minute you touch those wires the insulation crumbles like dust. So be prepared to re-wire. Don�t be foolish like I was and use electrical tape. The method I settled on was to buy shrink tubing, wire, wire ties and heat gun and soldering iron. $50 total on Amazon. I�m not sure of the exact AWG wire to use. Snip each of the real bad wires one by one. Place a shrink tube behind the splice. When done slide the tubing over the exposed copper and use a heat gun to finish it. Took me 3 hours to do each headlight. Be careful to match the correct connectors for hi and low beam. also� 1) Don�t force the headlights into the enclosure when done. Easy does it. Else you can crack the mounting bracket where the connector goes like I did. 50 f-bombs later I glued it back together and got it fixed. 2) Make sure to check your directional bulbs also. Those wires also corrode and lose their insulation. I found both of mine needed to be reworked just like the inside ones. 3) Lock the lights back in place with the tool. My right side blinker stopped working after my first attempt. Cost me 100 f-bombs. Fast blinker on the dash. It�s NOT the bulb! OK. Was it worth it? Not sure yet. I was thrilled to see all the lights working. Now need to drive at night and heat these up and make sure nothing blows up. Parts = $50-75 F-bombs = >500 PITA scale = 9 DIY enjoyment = 7-8 You gotta love Amazon. Parts arrived same day in most cases. You gotta love the 996. It keeps you busy and is a thrill to own and drive.
