Not very hard to adjust. It is just very time consuming. You need a wide bit phillips-head screwdriver, or you can find out what size the allen-wrench that fits into the socket is. If you open the hhod, and look straight down on the top of the headlights, you will see in the middle a post the extrudes from the headlights. Then you will see a place to isert a large phillips-head screwdriver. If you insert the screwdriver there you will be able to adjust the beam up and down. However I do not recomend this way. I suggest that you use the allen wrench method. once again if you are looking at the same post the comes off of the back of the headlights, then look behind where you would insert a phillipshead screwdriver, and you will see where you can also use an allen-wrench at the very and of the post. See the projectors that you purchased are a make named Depo. they are the cheapest on the market, but you can still have good results with them it just takes a lot of time and pattience. But anyways what I am trying to get at is I suggest you use the allen-wrench cuz the little gear that they made the phillips-head adjustment on is made of plastic, and when I adjusted mine I broke the gear. This is absolutly unaviodable, my friend did it to 2 sets of depo headlight projectors. But if you use the allen-wrench method the little gear will not break and it will be easier to turn the allen-wrench. If you insist on using the phillips-head way, and you strip the little gear no worries, you can still use the allen-wrench it will jst be harder to turn. You will most likely need to go and buy an allen-wrench to fit the socket, because it is very large. I can not remember what size it is, but I keep mine in the little tool box inside my trunk lid. I hope this helps. Leme know if you have any other guestions.
Oh yeah I forgot!!!!!!!!!!!!! to adjust left and right look at the outsides of the the headlights (closest to the fenders, but still on the back of the headlight), and use the same technique there. the adjustment post is constructed the same way on those as it is for the up and down. And go do this against a wall. Move your car about 10-15ft away from the wall, and adjust the headlights so that they are straigh out, and down about 10degrees, so that you do not blind other drivers. Well good luck, and leme know if you need anymore help.
