My M500s main incandescent lamp works but the LEDs don . Whats wrong?
Either you have installed the batteries in the battery magazine incorrectly or you have installed the battery magazine in the WeaponLight incorrectly. To fix the problem: • Remove the battery magazine from the M500’s battery compartment and verify that the batteries are installed with correctly polarity forward—it’s marked on the magazine. • Replace the full battery magazine in the M500’s battery compartment in the correct direction — that is, with positive (+) polarity forward. If the LED’s still do not turn on, call SureFire at 1-800-828-8809 and ask for Customer Service.
