Low or High Beams Don’t Turn On (for Hi/Lo, Bi-Xenon kits)
• The polarity setting must be changed until the low and high beams turn on appropriately.
• If this is a Hi/Lo kit and all polarity settings have been attempted but the low beams still don’t turn on, then the vehicle has a double ground. A relay will be required to power the low beams.
• If this is a kit with a relay and all polarity settings have been attempted but either the low or high beams don’t turn on, then it is possible that there are malfunctioning parts.
