new window switch --> bright LED

[Wallace White]

Aaron -

LEDs do get dimmer over time. IIRC, they are rated by the amount of time
they can run before the brightness is reduced to 50% of initial. Not
sure whether the falloff is linear or what. Typical numbers are around
10k hours these days, though they might've been less when our cars were
built? Also, running excessive current shortens the life.

Let's see: I average ~35 MPH, so 10k hours would take 350k miles. I'd
better go ahead and schedule my big LED replacement in another 160k! ;)
