dc2 headlights have 2 cog type adjusters on the back of the headlight, both are 10mm heads but one has a flat screwdriver head also. these need to be adjusted but i dont know which way you would need to turn them.
civic headlights have 2 adjusters also on the rear of the light, but have allen key heads. these need to be adjusted, but again i dont know which way to turn them.
