OPP ULITE 12LED Amber Emergency Hazard Strobe Warning Grille Working Light Bar for 12-24V Car Vehicle, Waterproof Safety Flashing Beacon Light for Truck Van Trailer Caravan Camper(CB-02-4PCS)

No fitting instructions but Easy enough to fit. Plenty of different light patterns to use. Yellow wire contacting the black wire changed the light sequence. White wire for syncing all the lights together works great. Side note as ive seen people say that your stuck on one pattern when syncing the lights. You need to individually select the pattern you want for all lights BEFORE you connect all the lights together with the white wire.

Ordered these for the back end of my concrete mixer, as originals had died or had broken wires. Easy to fit and change the flash mode, just by touching the yellow wire core on the black earth wire core once to change the effect. Happy with brightness too.

Great quality Would be nice to have available a generic wiring loom however the product is spot on

Decent enough lights, bright, easy to install and mount to vehicle. Wiring is easy only downside is when synced they all use the same flash pattern and can’t alternate. But can’t really complain for the price.

Bought around 20 of these to fit on 2 trucks had them all done professionally fitted after a week most of them had condensation in some of them worked ok the rest didn't even light up and then they lost there signals some just stayed on permanent others flashed as they wanted not in sequence not have for what they cost and to be fitted can not just take off and return they are live on work vehicles absolutely disgusting customer service no refund or replacements offered !!!!!!!!

A very good product

Uses for the front and the back of my van

Very cheap units the leds went out within days of fitting them.
