I have done the mod to enable the lights at any speed using the jumper inside the box and worked fine in the afternoon.

I came to test it at night, the driver side didn't work nor the switch light. The passenger side work fine even while in motion.

what could be the problem?

I'm afraid that i kept it on and forgotten to turn it off, will it burn the light/fuse?

 

No, just drain down the battery until the BSM kicks in. You need to recheck your jumper to ensure it did not come loose.
