I'm not an electronics engineer but I'm pretty sure must LED's can only handle 1.7V-3.4V input so I'm pretty sure those are going to burn out in a hurry.

Unless I'm missing something, please someone correct me if I'm wrong.

I like the concept though, and all you'd have to is add a resistor to the circuit and you're stylin. Or if you put sets of 3 in series (=10.2V) that might work without using a resistor, but brightness might be reduced

I have brake lights head lights and a set of yellow and bumper lights all strung together wit ha switch and my battery is getting warm so I think I need to pull the switch and just add a to the receiver pack dot want to risk a battery fire or something else that I could have been preventable. but wondering if anyone else had had or done this just with a 9v battery and experienced there battery getting warm
