I think I had a 921 in there to begin with. I replaced the original quite a while ago to increase the brightness. I imagine that's what caused the plastic lens to get brittle. Now I have no lens but it's nice & bright. I've thought about placing a couple of under cabinet puck lights up there but just haven't done it yet.Be careful and check the power limits on the hood light. The power limit on my range hood is 10 watts and I replaced it with a 906 bulb at 9 (ish) watts. I couldn't find a 10 watt bulb, but the 921 runs beyond 10 watts. For example 921 bulb: http://www.donsbulbs.com/cgi-bin/r/b.pl/921~usa.html vs 906 bulb: http://www.donsbulbs.com/cgi-bin/r/b.pl/906.html
Foil seems like a good idea and I will try this approach.
This one would work without rotating the base. A little more money though. Click Here
Oops, I didn't notice that. I did see a very expensive one at the Rally from coil n wrap but they were $25 each.Not sure, though. That side-firing one comes in a T10 base. The 921's are a T15, according to their website. I checked the 906/921 models they have and none are the side-firing type. I don't know what the difference in the base is without actually seeing one.
We bought a 3 pack of wired puck LED lights for Lowes/HD, cut off the transformer, and put them on the hood for light and added a switch. Have done this in the last 2 trailers and it works great. Lots of light.
