I have led lights under my tailgate, and i was wondering if i could have the three in the middlerunning lights and brake lights, and have the two on either side running and then have the two turning signals as well
This is what my lights look like with just the two wires i have 7 of these under my tailgate except they are red

 

May I suggest an OPTIX brand LED tailgate strip?? don't know where you live but we have Advance auto parts here in Florida that carries them-its a 60" strip that affixes with 3m double sided tape to the panel thats part of the bed between the bumper and tailgate, these are very cool and offed full lenght running lights, brake lights, and split rh/lh for turn signals, it plugs into a standard 4 wire flat trailer connector.

 

I know you can buy those light bars but i want to be different and do it with the light i all ready have

 

I don't think those will work if they are single brightness lights. You will need to purchase 2 level lights. (will have 3 wires). On the back of those, does the mounting hole have a metal ring around it for the ground or is one of the 2 pigtails the ground?

If you purchase some dual brightness, then it would be easy to make them do what you want.
