You can get away with just changing the glass but its not ideal - the beams will not aim correctly.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

My 1979 911 SC is left hand drive and still has the original headlamps. I know I will get pull at the MOT on them so I want to change them to UK spec. but Can I just change the lens? or do I have to change the whole head lamp unit? Thanks, Simber. Migration info. Legacy thread was 11595

POST 2Original post

Hi Simber, You can get away with just changing the glass but its not ideal - the beams will not aim correctly. Best bet is to change them for UK RHD - its the only way you can get assymetric beams and the correct aim. (Later 993 lights are switchable from LHD to RHD, but this only makes the beam symetrical, so doesn't light up pedestrians, roadsigns etc.) You should be able to get 2nd hand headlamp units and then put new glass in which will be cheaper then buying the whole units new. Migration info. Legacy thread was 11609

POST 3Original post

I have two complete lamps brand new in boxes if you can collect from Hampshire - they dont have the headlamp raise / lower mechanism. You can have them for a silly price! Migration info. Legacy thread was 11628

POST 4 / ORIGINAL POSTEROriginal post
