burnt aux.(Baja) light. I geuss the whole lamp assembly has to be replaced? as opossed to just the bulb.

 

You can change out the bulbs (they are common H3, or is it H4?, auto bulbs), but you have to take the housing apart to do it. Its a PITA. When I installed mine (I have a regular DS) I used small bolts and nuts to put the housing together instead of rivets. This allows me to loosen two bolts and then swing the outer portion of the housing forward to get to the bulbs. That makes it a little easier, I suppose.

 

The BAJA lights are an H3 bulb.

I have replaced mine with an H3 HID bulb...
