Over the past 3 years, I've lost count on the number of times the front bumper on my Celica has been swapped (50 to 75 times ???). I've gone through two packages of side marker lighting during this time. The lighting usually had gone bad during the swap of removing the lighting from the side marker housing and dropping it onto the plastics, just to get it out of the way while I pull the bumper off with the other hand.
the lighting for the corners is so inexpensive and incredibly easy to replace, that there really is no worry about it
I just recently replaced my rear turn signals and such with POLARG SUPER REDS / brighter lighting - the cost on doing that was ALSO under $10. no big deal and easy enough to do.
