Have a kouki, stock is h1 55w. I dont want to retrofit hid but would like to use some 70w bulbs I picked up cheap. \


Pulled my housings apart to paint them and saw the 55w had burned the chrome off the top of the reflector a bit. this part is plastic.
So how much hotter would 20w make it?
Anyone been running 70 100 110?

I have already made a upgraded harness with relays and 10ga wiring. 20amp fuses.


flame away if you think this is inappropriate .

some research says metal not glass housing can work with it, but nobody reply on using in kouki

The thing is, you want more lumens directed to the front of your car, not more power hungry bulbs. True, most of the time you get more lumens, but if the glass and reflector are bad, it will do nothing more than heat and load your alternator. I know phillips make some lamps with significant more lumens than standard 55W bulbs, yet they still require only 55W.

You can also get better glass and reflector. TBH, ebay "cristal" jobbies can be significantly better than a 20 Y.O tarnished oem reflector and badly surfaced glass. Just dont get "dark reflectors", these will completely absorb the light.

I installed both of these upgrades, as i did not want to go HID either, and well... it works.

You may want to try that too. And it wont melt.

How hot 20W more leads depends on airflow (aka none) and air temp, so it is quite hard to tell. But it goes exponentially. If it burned the reflector, that is already "too hot", and it will surely have tarnished the reflector.
