I got the LED's a small wafer board (a circuit board with lots of holes), a conductor pen (a drawing pen filled with liquid metal (to draw the circuits) and took it home and soldered everything together, and then soldered wires to the contacts and put female terminals on them, (incase I need to replace it I dont have to cut and resolder).

I mixed up the LED's White-Blue-White-Blue.. You get it.... And it is very bright.

LED's- $12.00
Circuit Board- $3.00
Solder pen- $5.00
Total cost: 20.00

And it should last the lifetime of the dome light cover....
