So, with Philips and Osram and the likes offering LED "bulbs" to retrofit to classic car headlights fitting e.g. H1 or H4 bulbs, Porsche Classic has finally certified a retrofit kit for the 993 at a reasonable price. Talking to my local dealer however, the LEDs are designed to replace the factory standard halogen bulbs and not intended as a 1:1 replacement for the original Litronic xenons. Litronic obviously has a separate voltage conditioner and power limiter. Am I overlooking anything if I simply remove the factory Litronic voltage conditioner along with the old xenon bulbs to fit the LED "bulbs" from Porsche Classic?

I think you’re assuming halogen and xenon bulbs are interchangeable as far as how they clip into the headlamp; pretty sure they’re not.

I just bought some of these H1 LEDs that were supposed to be a straight plug and play replacement for the OEM bulbs in my 993.

they were suggested by somebody on the 911UK 993 forum.

but when I plug them into my car and turn the lights on they light up for about 1 second before blowing the fuse.

I've emailed the supplier asking if I'm doing something wrong or I have bought the wrong bulbs.
