robb1 Posted May 2, 2006 Share Posted May 2, 2006 Hello.................Question is for a 98 Impreza OBS. Does anyone know or can identify which screw does what for headlamp aiming adjustments? Two on each of the headlights. Just want to adjust the up /down ....not side to side. Thank You very much for all answers!!!! Quote Link to comment Share on other sites More sharing options...
robb1 Posted May 3, 2006 Author Share Posted May 3, 2006 guess the only thing members like to talk about are timing belts, interference engines and head gasket issues.................... Quote Link to comment Share on other sites More sharing options...
cookie Posted May 3, 2006 Share Posted May 3, 2006 That's not something a lot of us do at home. I have only done it in a shop with a headlight target chart. If you must do it at home face a wall with your car and turn on the lights. Mark where the car is now and mark the wall with masking tape in an x in the center. I have seen the up and down on both top and bottom of a light, but if you use the tape you can put it back if you screw up, as well as see your change.

Subaru_for_LIfe Posted May 3, 2006 Share Posted May 3, 2006 Hi Robb1, the screw that's closest to the outside of the car (fender) adjusts for the horizontal and the other screw that's closer to the center adjusts the vertical. Atleast that's what Haynes manual says. Have fun. Quote Link to comment Share on other sites More sharing options...
Wayne Boncyk Posted May 3, 2006 Share Posted May 3, 2006 cookie's right - most people do this so seldom that we have to "re-learn" which one does what by trial and error. If you point the car at a shady wall (or do this at night), mark the bright spot from your headlights on that wall with some tape, you can then see how each spot moves in response to each adjustment and figure out where you want the re-aim point to be.
