Frequently Asked Questions
Are these strobe lights legal for public road use?
Legality depends on your region and vehicle type. Many areas allow amber warning lights on commercial or emergency vehicles but restrict red or blue lights. Always check local traffic laws before installation.
Do the magnetic bases damage my vehicle paint?
High quality magnetic bases often include protective rubber cups to prevent scratches. However regular inspection is advised to ensure no debris gets trapped under the magnet which could scratch the surface.
How do I clean the lenses without scratching them?
Use a soft microfiber cloth and mild soapy water to wipe the lenses gently. Avoid abrasive cleaners or rough cloths that might cause micro-scratches reducing light clarity over time.
What is the typical lifespan of LED strobe lights?
