My right tail light has, once again, burned out. This happens seemingly 1-3 times per year.
I use good quality replacement bulbs, and the left tail light has only burned out maybe 1-2 times in 5 years. The right tail light is completely out, for both normal operating and for braking. Oddly, the dashboard warning indicators - the 'lamp-out' icon and the yellow ! indicator - only come on when I hit the brakes. Otherwise, the dash doesn't show the lamp as being out.
Any thoughts on a) why the right one (and only the right one) burns out so often, and b) why the indicators only come on when braking? I assume some electrical issue, but I'm not sure where to start. Any assistance would be appreciated. Thanks.
