Video: C5 Turn signal bulbs keep going out?

[DocOhm]

Many C5s have a problem where the top of the turn signal gets cracks in it from the heat of the bulb. When it gets wet water gets in there and breaks the light bulb. Here's a video on how to fix that using JB weld. It's been many years since I've fixed mine and I haven't changed a bulb since I did this fix.

Probably a good idea to replace the incandescent bulbs with led's while you have it apart. They run much cooler and pretty much guarantee the fix is permanent. You can buy replacement lens assemblies for about $60.00 each if you don't want to deal with repairs.
