I don't know if the Polarg M-28 is new or not (I've never heard of them before), but I had a pair of Minimax bulbs on back order with eautoworks.com and the guy told me the Minimax were discontinued and offered the Polarg M-28. Anyway, they're pretty cool, they're 1.5" 10W bulb that matches my existing M-4 interior lights. For those of you trying to use M-16, try the M-28.

It seems a lot brighter than the stock bulb. They come in a pair for $14.95.
