Guessing the designers uses 3W x7 bulbs = 21W to balance with the two 21W brake filaments on each side?

I usually use the Osram or PHILIPS warm white LEDs, but think these might be a bit bright.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hi, Just wondering what type of bulbs go into the high level rear brake light unit please? C2.1 996. Are these regular bulbs, or can LEDs be used? Thanks!

POST 2Original post

I expect them to be the same as other 996 variants. Part number 900-631-019-90 12v T10 W3W. I replaced mine with LEDs. I used these: https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/133024346660 You need seven bulbs for the additional brake light. It's the same setup for the spoiler brake light.

POST 4Original post

Just a word of caution if your changing the bulbs in the retractable spoiler brake light, over time the heat from the engine can make these quite brittle, when I opened mine up to replace a bulb a few of the bulb holder securing tabs came off, rather than £100+ for a new light unit I fixed my old one by soldering the bulb holders to the power supply rails :thumb:

POST 5Original post

Depends on your view of originality, I bought an aftermarket LED replacement off the internet, LED and it was £56.

POST 6 / ORIGINAL POSTEROriginal post

Thanks for all the tips! Had forgotten the brake lights in the spoiler itself. I decided to order some basic halogen capsule Osram W3W and a "trim tool" to try to avoid breaking the tabs... I usually use the Osram or PHILIPS warm white LEDs, but think these might be a bit bright. Guessing the designers uses 3W x7 bulbs = 21W to balance with the two 21W brake filaments on each side?

POST 7Original post

POST 8Original post

Mike, Did the LED one come with a gasket / seal? Ian

POST 9Original post

Hi Ian, yes, it has a soft rubber seal 'stuck' in place around the plastic rim. Mike
