You can always spray the inside of the light with the "chrome" spray paint, or put some aluminum foil behind the bulb holder and keep it in place with some silicone glue. What is the bulb number? I have found some brighter bulbs that are the same size as their less impressive cousins, and have used them. Only thing that you have to be careful about is if the bulb is too close to the lens, then it might melt the plastic.
