What is the 306 XT headlight type?

yes what are my friends?

Maybe I can help if you write a little more clearly when saying headlight type but if you are talking about the bulb, I know H4.

evt bulb here i bought xenon before i bought h4 long short xenon light up. I got it wrong, they said h1 buy it right, I don't know: S

I think it would be best to stop by the electrician and learn from him and wear what he said :)
