Has any body found a solution for exploding turn signal lamps?? I will have to pull lenses out to shake all the busted lamp glass out of them.

 

Most likely culprit is water leaking into the turn signal area from car washes,rain,etc. It's a pain in he *** but what can you do?

 

Get new housings or seal the burn holes in the old ones and install LED bulbs from JWM. The LEDs won't melt your housings like the incandescents do.

 

Who is JWM?

 

I found them. Will the LED's break if they get wet?

 

Good advice above.

Melted turn signal housings are common and its a design problem on all C5s. The turn signal bulbs are dual filament and act as park, turn and DRLs. The heat of the DRLs being on constantly burns the housing. I had to inhibit the DRLs here in England as ambers are not legal here. I never have T/S bulb failures and my lenses are still sound. The most common symptom is that the bulbs fail regularly because water gets into the bulb holder.

You can inhibit the DRLs by pulling the A2 fuse but if you want to keep the DRLs, LEDs are the way to go. LED bulbs produce less heat and are less likely to damage the housing. If you fit LEDs you’ll need a ballast mod to prevent “hyperflashing” as the system doesn’t recognize the LED bulb and thinks it’s failed. (JWMotoring sell a harness which will fix that issue).

Pull the housing – I’ve attached a procedure below – and inspect it. Others prefer to go in through the headlight housing but its harder to see the fixtures. You’ll probably find a hole on top. If it’s not too bad seal it with silicon sealant and reinstall the housing. That should fix the problem for now and the silicon may be enough to stop it getting worse.

10. Remove the lamp from the bracket.
Installation Procedure
1. Install the front park/turn signal and sidemarker lamp into position on the front turn signal lamp bracket.
Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
2. Install the front park/turn signal and sidemarker lamp to bracket retaining screws.
Tighten
Tighten the front park/turn signal and sidemarker lamp to bracket retaining screws to 2 N•m (18 lb in).
3. Install the sockets to the lamp.
4. Install the lamp, with the bracket, to the front fascia.
5. Align the lamp to the opening in the front fascia and hold the lamp firmly in place against the fascia, while installing the front turn signal lamp bracket retaining screws.
Tighten
Tighten the front turn signal lamp bracket retaining screws to 3 N•m (27 lb in).
6. Install the lamp bracket retaining spring to the front fascia.
7. Install the front turn signal lamp bracket retaining spring to the lamp bracket.
8. Position the brake caliper cooling duct to the front fascia and press the duct toward the fascia to secure.
9. Install the front fascia lower closeout panel. Refer to Close Out Panel - Front Bumper Fascia Lower in Bumpers.

 

A good writeup from DeeGee. I replaced my original corners - they were almost melted through. Installed after-market clear & black corners and LED switchbacks from JWM Motoring; makes a stylish upgrade.
