Need red led bulbs for puck lights

[TX_Arvee]

Has anyone seen red LED bulbs for the small circular lights, these are the light bulbs that have two pins with a smaller bulb, maybe 1/2" long and 1/4" or so in diameter. The light cover is glass and 3-4" in diameter.

I would like a couple red LEDs so the kids can leave them on while traveling and not bug me while driving.

I have found lots of colored LEDs bulbs on Ebay. Can you post an image of one, that would really help identifying the type/style of bulb.
