I'm refurbishing 'Hazel's' front end whilst I'm changing the radiator & thought about wiring some extra LED sidelights into the halogen bowls. I have LED bulbs in the actual sidelights which are MUCH brighter than the originals & I'm thinking some in the outer headlamps will make good 'running lights' that every car seems to have these days. I'm getting concerned that my P6 doesn't standout any more against traffic with such lights.
Anyway, these are the backs of the headlamps with a suitable old-style bulb & holder. Can anyone tell me what to look for to get LED replacements that will fit these holes? I thought it would be easy, but can't find anything like.
