SOURCE: replace low beam headlight on 2003 chevy trailblazer
I just replaced the low-beam bulb on my 2003 Chevy Trailblazer. The grill just needs to be loosed slightly. Then, raise two L shaped brackets, one on each side. For the inside one, I needed to use a flathead screwdriver to get to it. The light assembly can then be pulled out. Remove the rubber cover and rotate the bulb one quarter turn left to release it. Pull out the bulb, replace with a new one ($11.50) from Advance Auto Parts, and reverse the process. Once I figured it out, took about 10 minutes total.
