Reveeen Posted November 14, 2007 Share Posted November 14, 2007 Quickly (because I'm not that familiar) Stock Subaru lighting is like most Japanese type lighting, the lights are switched (hi-lo) through a "moving ground", rather than the conventional way (moving hot, or +). Mounting "grounded" aftermarket headlights will fry the headlight circuit, and if they do work at all, they won't work properly. 1 relay, you should be able to do the light thing with 1 relay, OEM, or aftermarket. Alternator output in stock alternators is not very high. Link to comment Share on other sites More sharing options...

beataru Posted November 15, 2007 Share Posted November 15, 2007 Just relaying your headlight circuit will brighten your lights quite a bit. Link to comment Share on other sites More sharing options...
Reveeen Posted November 15, 2007 Share Posted November 15, 2007 1) take a test light to your headlight connector and find out what you have. 2) there should be a steady + and the - should travel between the remaining two connectors depending on the beam selection. 3) I believe that your headlight relay and fuse are to be found in the box beside your battery, 4) repair the system so that it works properly stock before heading into the unknown.

The Dude Abides Posted November 16, 2007 Share Posted November 16, 2007 i had that problem on my 88 dl with the quad headlight setup. I came to findout that i had the original lights from the factory. I replaced them with sylvania silverstars. They are bright white lights not blue. Those are buy far the only headlights i will ever use. You dont need to convert anything over. Its strictly a plug and play system. I can see 10 times better then i originally could. On top of that i replaced them in my minivan after one of the factory ones burnt out. They are much brighter then any factory light other then the expensive car lights.
