Using a converter to power headlights
Hi,
I am wanting to fit a pair of LED headlamps with angel eyes to the old car, however it is a 6 volt system and there are none available for that
voltage. I was thinking I could use one of these to "boost" the voltage up to what is required. Not sure of the power required by these but
10amps seems plenty to power two LED lights?
A good idea or stupid??

I'm involved in a discussion on the caterham site about the quality of the Chinese LED headlights (and the lack of a beam pattern). No idea if
your idea would work but be careful as it seems lots do not (despite claims) meet the beam pattern requirements.

the converter should work
but I think the car would end up looking like a bugeyed monster.
have you considered just changing the bulb, (know led bulbs in standard headlight fittings will not meet mot requirements, but ok for very old
cars)

I have already got the LED conversion bulbs and their ok but I want to try something different (that can always be put back to original), I'm
using the car quite a bit in the evening and need good lighting. I also like the angel eyes and they look nice on older cars with headlight pods 
might get the ones with that change to orange too so I can ditch the motorbike indicators. It's MOT except so I can really do whatever I want
with the lights, was thinking of 3D printing new rear lenses with LED's built into them

Thanks, I'll do some research into ones with good recommendations.

I run LEDs in my H4 reflectors, they have near identical beam pattern to normal bulbs and pass the MOT because they are friendly, but pointed out they
shouldnt but let it slide because the pattern is fine. The boost converter will work fine if the current capability is high enough, no problem.
Fwiw id try them without the converter first, they often have a fixed current driver which accepts a very wide input voltage range ans theyre only a
3v LED usually, so its possible theyre going to work anyway. In the next day or so I'll get my adjustable psu back and can test it.

I don't know why they changed the rules. If a replacement LED bulb gives the right pattern, why should it be treated any differently than a whole
new LED sealed unit?
