I discussed these with my neighbor and we agreed that these should be installed under the hood with a switch (they're waterproof, after all) on one of our vehicles for a trial.

Also, of note, the SuperBriteLights site has LED capsules for Gen 2's for $100 for a set of two, ready to drop in...hmmmm.

For anyone thinking of LED's for use behind a lens, make sure to use the same color bulb as the lens or it will look funny.
