A thread started by ECS over on the Zine got me thinking. They are advertising a set of LED reverse light bulbs for $49.95 :o There has to be a cheaper alternative.
I looked up the bulb using the Sylvania site below and came up with a 7506.
Then shopped around a little on superbrightleds and came up with these.

Which do you think would be a good equivalent?
