can i replace my neutral light bulb with an led without any transformers?

[cbr929rr]

After a couple of dead batteries from leaving the 400ex in the garage with the key on, I was wondering if i could remove the filament bulb and add a led. This would have almost no draw on the battery but I don't want more complicated wiring with transformers.

LED's (light emitting diodes) do not use transformers. Depending on the LED you want to put in there, you DO have to install a resistor in line to bring the line voltage down to the specification of the LED if the LED is not 12vdc capable, otherwise you will likely ruin the LED quickly.

yeah, turning the key off works the best.
