Headlight advice.


Part Of The Furniture
Hey up guys I've got a problem with both headlights they work but are about the same strength as a tea light and really not able to see as well as I have been able to in the past, I've been staring at the Haynes manual for the past half hour and now my head hurts just lots of lines going to boxes I can't see... Must admit I'm guilty of wanting to throw in the towel on this car if it's not one thing it's the other.
It looks like my headlights are sharing one single 12v current but don't know how to go about sorting it I'm really confused :/
Cheers Tom.
