LED Blackout taillights

Does anyone know if the LED portion of these taillights will work with 12V power? Or know what 12v bulb would work in the socket? I put 12v to the small square LED board and it lit up (pretty dim) but it was in the daylight, and I put 12v to the red board but couldnt see anything happening. Dont really need them as I'm not planning on doing any night time combat convoys. I will however be using the upper two bulbs and have already checked them with 12v bulbs to make sure they work.

I bought some of those red LEDs off eBay the other day, I can't wait to try them out on the Deuce. I think you should still be able to see them light up in daylight if they were going to, I bet they require full 24v. UNK which part number 12v bulb is required.

Unless you plan on doing BO driving, there is really no need for them.
