Re: H7 high beam watts
I have them for years, the low beams are cycled every nite you drive. They are gas discharge lamps and the power supplies are the issue if your get low cost units. It is the heat dissipation that causes the LED units to require OEM designs and not allow them for retrofit kits. That is the real way to go.
My Hids are SOOOOO much better than the incandescent lamps that I put them in my RAM truck now I can see. The ram head light is a single lamp that magnetically shifts position for high beam and never has to switch on and off. Wish that could be used in the C but the lense is not set up for it. The RAM has but two lamps and the stock lamps were terrible.
