Frax Posted December 27, 2010 Share Posted December 27, 2010 Hi and welcome. Most or the replacement light is a straight fit – plug in and yer away. Easy job if there is no rust in the headlight bezel. Frax Quote Link to comment Share on other sites More sharing options...
western Posted December 27, 2010 Share Posted December 27, 2010 Straight fit as mentioned above, you can run the dip & main beam via relays & thicker wires to improve the current flow & take the load of the main light switch. Quote Link to comment Share on other sites More sharing options...

LandyManLuke Posted December 27, 2010 Share Posted December 27, 2010 What's the voltage across the bulb when its on? you'll probably find due to poor earting and old wiring, you've not got a decent 12v at the bulb. Quote Link to comment Share on other sites More sharing options...
