two bolts on the top of the plastic housing - lift the plastic headlight out and unscrew the headlight from the bottom of the light- replace the bulb and be sure to get the plastic pins in the right spot before you bolt the headlight back in place.

Low beam bulb burnt out? Replace bulb. Bulbs OK? If the dimmer switch is also the turn signal/cruise/headlight on and off switch, you probably have to replace the entire switch.
pop the hood and unscrew the plastic caps that hold the bulbs and and replace with new bulbs
could be a couple things did you check your fuses? bulbs could be burnt out, and only giving normal headlights, might want to replace you might need to replace the headlight/highbeam arm that stick out of your steering coloumn. cheapest thing first. start with fuses, then bulbs etc. it will also look like your high beams arent working if you have a build up of dirt on them, it will dim the light significantly.
It is true to say that Halo headlights bulbs can be replaced.
