The gear I mentioned that gets hot/brittle and breaks over time isn't the worm gear though, it's the gear with the metal arm in it. (I haven't had a worm gear break yet. The worm gears are the ones actually on the motor shaft.) That gear (with the pivot holes in it for the metal arm) is hard to find/replace so that's the one I bought/modified from HobbyTown USA. The funny part, the gears from HobbyTown were meant to be used in RC cars, but I found one the right size and drlled a pivot hole in it and it worked. I think the oscillating gears/pods will be fairly hard to find unfortunately, especially if you want a lot of them. I've only seen one here and there, not very often. Who knows though, someone may see this who has a stockpile of them. (I'd like to buy some extra gears for the little metal arm myself for the ones I have.)
If you want "straight forward" lights only, they make the stationary lights. Of course, you can wire those up as "steady burn" or you can wire up flashers to them so they blink/flash. If you want to use Vector pods you could use the stationary takedown/flasher reflectors they had, but don't see a lot of them for sale either. (Or smart pods like Jennifer mentioned maybe because you can set them for forward light only. The smart pods oscillate, flash or just stay on steady depending on which setting you choose.)
If you can't find enough of the TCL's, Oscillating pods or enough stationary reflectors for your project you could "cheat" a little bit if you had to....
If you used a motorized pod, position the reflector in it in the direction you wanted it to point/show light then wire the light only to turn on and leave the motor unpowered so it wouldn't spin and shine at you. See what I mean?? (The reflector might move a little over time and need readjusted this way though from vibration, etc.) There's two wires for power, one is for the light and one for the motor. With the motor attached in place with the gears you can turn the worm gear, by hand, to where you want to point the reflector. Then when you wire it up only wire the light to come on, not the motor. It "should" more or less stay in that position then if you turn the light on it'll have light, but the reflector won't spin since you shut the motor off. Then if you wanted to adjust the "aim" you can take the pod dome off, turn the worm gear a little with your finger and put the dome back on. There's so many options, just depends on what you decide to do and the parts you can find that work for you.
I sure talk a lot. It would be neat to see it when you finish the project. Have a good night!
