Onboard Flashlight

[DjScribbles]

After doing some additional searching, I found these:

They are automotive brake/turn lights, and a socket for easy mounting, and have a narrow beam angle.

Searching for 12v flashlight, worklight, etc yields primarily rechargeable lights, which wouldn't necessarily operate at their charging voltage.
Thanks for the correction on R50.

I'm still curious what other solutions other teams use, if they are willing to share. Knowing what you need is typically much easier than finding what you need.

We used this:

These are great for this application because they are current controlled and thus will run on almost any voltage. They are very bright, very light, tightly focused, and are only about 2" deep.

We just hooked it up to the PDB through a few 7801 voltage regulators. We ended up not using it for competition because the light that we had selected was perfect for our vision code people (it was even the right shade of green!), but was not focused enough for manual targeting. (Sorry, I don't have a product number, but it was originally intended to be mounted on a gun or something.)
We should have ran it through a spike relay, but did not have the time. I will also say that even running our light through two 1-amp 7805s run in parallel with a heatsink was not enough to power the light for more than a minute or so without getting scary hot.

Thanks for the example! I'm debating using this for aiming ourselves.
