Then when your cruise control suddenly stops working, you know one of the hidden bulbs has burned out.

I'd like to go with LEDs, but am waiting for you guys to finish your testing.

Actually I believe the DIC (Driver's Info Center) displays a message when a light burns out.

Plus, you get the benefit that even though the (hidden) light is burnt out, the exposed light is still working. But, yes, the cruise control, would be not working properly.

A student was following me to the pool last night and when we arrived he told me that while the yellow beast was easy to follow ( ), the turn signals seemed to be very weak. When I got home, I turned on the 4-way flashers and the amber lights appeared to be plenty bright. I wonder if they go dim when the brakes are being applied? I'm going to have my wife sit in the truck tonight and apply the brakes to see if they do go dimmer. Any of you that switched to the LEDs run into this?
