Will a Reverse Alert 3156 Bulb Replace a 3057 Bulb  

Question:

Expert Reply:

Yes, the Hopkins Backup Alert Replacement Bulb # HM20101VA will work for you. The 3057 and 3156 bulbs are very similar with the only difference being that the 3057 bulb is a dual filament bulb typically found in blinker/tail light applications. However, a dual filament will work fine in a single filament application like your situation.
