npvpositive Posted 18March, 2018 Report Share Posted 18March, 2018 See link below to John Audette's website. He is the "Porsche light guru" and has forgotten more about H1/H4 than the rest of us will ever know! Put simply, H1 has two reflectors and two bulbs (one for high beam, one for low). H4 has one bulb and one reflector. The H4 was introduced in 1972, but you see them on lots of older cars because Bosch stopped manufacturing the H1 and they eventually became almost impossible to source. These days a fully restored set of genuine H1 lights (when they are occasionally available) sells for about US$1,800. I think it's fair to say that only the most pedantic Porsche fans will "call out" an older car for having H4s instead of the correct H1s. http://www.audettecollection.com/h1/ Link to comment Share on other sites More sharing options...

9er Posted 18March, 2018 Report Share Posted 18March, 2018 As Nick says the H4 are the best bet however yours being an early car it really needs the lenses without the ledge at the top. Audette goes into better detail. This is H1 but I just included it to show the lense shape I was referring to. Link to comment Share on other sites More sharing options...

Yes H1 lenses should be correct for your car. Do you know if these are illegal here? As I have been thinking about getting some too Link to comment Share on other sites More sharing options...
npvpositive Posted 19March, 2018 Report Share Posted 19March, 2018 Don't think you can put H1 lenses on an H4 core (if that's what you're suggesting?). The lenses are designed to work with two reflectors and two bulbs so they won't refract light in the correct direction if you have a different core with only one reflector/bulb (for example, an H4). Suspect the yellow is illegal, but I'm not certain. If so, it would give an insurance company a nice excuse to try and deny a claim if an accident occurred at night.

9er Posted 19March, 2018 Report Share Posted 19March, 2018 If your car is being done to a high level of originality definitely go for he H1 lights. Yellow is not legal here in SA. Link to comment Share on other sites More sharing options...
jakroo Posted 19March, 2018 Report Share Posted 19March, 2018 Outlaw is one thing, illegal and uninsured is an entirely different thing..... Yellow lenses are great for foggy or rainy conditions but are better off being either slip on covers, or dedicated spotlights..... These are clear versions of the H1 - https://www.ebay.com/itm/PORSCHE-911-912-H1-2-RHD-HEADLIGHT-LENSES-WITH-BOSCH-LETTERING/360497189059 Link to comment Share on other sites More sharing options...
ELSPORTO Posted 3April, 2018 Report Share Posted 3April, 2018 Turbo - get them from John Audette - he has been discounting them recently and they are perfect restorations of originals. When have you ever seen a yellow headlight on a car on the road in OZ? Link to comment Share on other sites More sharing options...

Mindfulness (Thankyou @SimonN ) it seems is paying dividend. For those who seek deep illumination: Carello, Cibie, Marchal and others made a twin reflector light The Biode ( carello and cibie) and amplilux ( marchal) these were de rigeur and ducks nuts.. for a time . Of course eclipsed or at least matched by the advent of H4’s and of course HID’S However, for period charm and cool correctness . These are must have I also have NOS biodes and amplilux .

T, i'm feeling like you don't care about H1's anymore, but in case you do, there is a NOS set on Early S for $2,000 USD .... you cannot do better than that.
