Try this, and there are more there.
Hope this helps.

possibly due to multi-function switch, turn on headlights, and EASILY wiggle around the directional stalk, see if lights come on, if so, theres your problem

to replace the headlight, the bumper should be removed, in order to expose the bottom bolts of the headlight. be carefull, on the side of the fenders where the bumper clips in, it usually breaks if manhandled. this will cause the bumper to clip out in the fender sides.

there is alot of stripping to get at them remove the bumper and the rest is plain sailing

If it is the headlight itself. There may be a cover or shroud on the front of the engin bay. Remove that, may be a combination of clips and screws. If it does not cever the light area, it is even easier. There will probably be 3 screws or nuts, remover these and unplug the electrical to the light. From there you should just be able to pop the light out of place. If you are just replacing the bulbs. Where the power goes into the assembly, turn the clip, may be grey in color and pull out of the headlight assembly and replace the light bulb. But don't touch the new bulb the oils from your skin will damage the bulb.

Just rotate the small knob at the left of your dashboard to the right. This will increase the lights of the dashboard.
