i got the clear dome style off ebay. you can hook them up through the front turn signals. i rewired my reverse lights and made them turn signals/brake lights so they would light with the brakes and blink if the blibker was on also, but i spliced them in to the front turn signals so decreasing the ohm load in the circuit and causing all the blinkers to flash half as often. (about once per second rather than twice) i dont know how to do it other tan this, so im gonna just wire them to the bumper lights. plus if you want them to blink you have to buy a dual filament bulb. i bought superwhite wedges to go in mine ($9) but the turn signal 2-filament superwhites were $17, so youll pay more for the bulbs too
