Simple $12+shipping and great results. Bought the bulbs on superbrightLEDs. They look identical to the $30 bulbs on AmericanMuscle but 1/3 of the price. (WLED-WHP5: Cool White)
Install was very easy except the darned LED bulbs don't fit into the plastic hole. If i had a drill or file on hand I would have lightly enlarged the hole. But since I didn't

I had to jam them in and hope they didn't break, got lucky that one made a cracking sound but nothing visible happened. Here is the result.
Sorry I forgot to take a before picture from outside the car. Note that this is inside a parking garage with so-so visibility.
