In order to help being seen while stopped in traffic, I added a pair of additional brake lights. I bought 2 of the super bright LED 1156 bulbs and mounted them inside the rear turn singnal housing. This was a simple mod that took about an hour, but if it saves me from getting blasted, it was well worth the time.
Used a dremel tool to cut the hole in the reflector and connected the wires right to the bulb(No room for a socket).
Hard to see the brightness in this pic, but compare them to the stock light with the brakes on.
