Frequently Asked Questions
Will These Lights Fit Oval or Non-Standard Mounting Holes?
They generally will not fit oval or non-standard mounting holes without modification. The responder notes mounting options are limited to pre-cut round openings; light compatibility may require adapters, trimming, or alternate grommets for secure installation.
Can the Lenses Be Replaced if Cracked?
They answer: lenses are moderately durable but can crack; replacement options are limited to contacting the manufacturer for spare lenses or replacing the entire unit. Warranty or returns may cover defects; aftermarket parts are uncommon.
Do They Require a Resistor When Used With Modern Vehicle Flasher Systems?
No; the lights typically do not need a resistor for resistor compatibility with most modern flasher systems. The person notes LEDs may cause hyperflash on some vehicles, so load resistors or an LED-compatible flasher can be used.
Are the Lights DOT or SAE Certified for Road Use?
Are they DOT or SAE certified for road use? The seller does not list DOT/SAE certification; purchasers should assume no certification, evaluating road safety and light durability accordingly and consult manufacturer documentation or local regulations before installation.
Can Multiple Lights Be Wired in Parallel Without Voltage Drop?
Yes, multiple lights can be wired in parallel. The reviewer notes proper wiring configurations and voltage considerations: use adequate gauge, fused supply, and secure grounds to prevent voltage drop and guarantee consistent brightness across all fixtures.
