Review on XT AUTO 6LED Car Truck Emergency Beacon Warning Hazard Flash Strobe Light White/White 4-pack: Maximize Safety with Brilliant Flashing Lights by Micheal Wolf

Good light overall. Excellent as secondary signal lights. During the day it is not as bright as we would like, but it is at night. WOW! Good! Good visibility even off center. I hooked everything up to a 5 amp circuit on my Blazer Wireless switch box along with a length of 18/3 extension cord I had laying around. Black (-), red (+) switch, yellow (+) switch momentarily. The yellow wire connects to a 3 amp circuit with other multi-flash indicators. Each lighting set has a physical snap switch mounted under the hood. Turn on the 3a circuit and press the momentary switch to change the flash pattern which lamp set i want to change then turn off the 3amp circuit. , momentarily touch yellow positively until both sides stay on. Now, once plugged in, all the lamps will go through the same flashing pattern. Mounting Tip: Drill only a 1/2" center hole. Use this gray heavy-duty double-sided mounting tape to tape to your mounting surface. 1/2" hole in the center of the tape. The 2.5cm wide tape fits perfectly on the back and provides a good watertight seal.
