I did what Nolam did using the 2 pack LED strips from Pep Boys, except I didnt have enough room to mount them between the grill and the fiberglass within the hood. I opted for running them in two parallel strips vertically down the hood under the grill about 3 or 4 inches apart.
I played around with a few different mounting positions and found that there was a sufficient slope to the pannel under the grill that running the LED strips downward was very visible from behind, especially at night when the LEDs seem to light up a good portion of the grill box.
Wiring was easy. I just tapped into the existing attachment for my driver's side brakelight. The hardest part is running the two wires from the grill, around the hinge and into the engine compartment. I took my time installing and think it took about 2-3 hours.
Hope that this helps, Grant
