neon wiring question
 

im goin to put two red 9" neons in the hatch area, the neons are already spliced together and ready to go...i also bought a toggle switch so i can use it like the rear light i.e, when i open the hatch, the neons light up...i was goin to wire up the toggle switch to the existing light wires, the green/red wire is negative and the green/blue is positive...i wired up the toggle switch and the switch worked because the switch lit up, but my neons didnt light up....how do i get my neons to light up????
