Lighting Upgrade

I've got the H4 upgrade for my Duster thats going in when I put it back together. I've always wanted brighter lights for the older cars :D I was looking at the wiring diagram for a 69 Cuda and it seems like the only way to do a third brake light is to tap into one of the brake lights. The only problem with that is that light is going to blink with which ever side you tap into when you use your turn signal. Otherwise its project time with the second switch :(

Those 1157 leds are pretty cool. They make them with different amounts of leds so you need to make sure you get one that will fit thru the hole in the housing.
