What would be really nice is if we can find some nice LED headlight bulbs for our cars.
After a quick Google, you can:
Phillips LED H4 Bulbs
So all you need to do is get the H4 conversion bulb kits as listed by someone else above, and then shove LED bulbs in it. The ones I linked are 21w bulbs and cost a fortune. I did notice there are some much cheaper ones out there, but the ones I saw seemed to be rated around 80w, which is quite odd for LEDs.
Dunno if the rated Lumens level would be ok, but a quick comparison to an Osram normal 55w H4 bulb and it seems comparable.
