Review on 🔍 Enhanced Search-Engine Optimized Whelen Engineering Vertex Super LED Light by Brian West

They're pretty bright if they can be mounted in the perfect position in the headlight or taillight housing. If you deviate slightly from the axis, you will be disappointed by the brightness. The instructions printed on the plastic bag they come in do not cover their programming for the phase. So they will be SOL if they all flash at the same time without YouTube. Still they don't alternate when I adjust the phase and all 4 are connected to the sync line. I need to run the rear wheels separately from the front wheels - the rear wheels sync with each other, the front wheels sync with each other, but not all front and rear wheels sync together. I have a feeling this should work, but then again - it doesn't work, and there's no guidance here on what to do. I also installed a beacon on the roof and wanted to sync it with them, but I really don't think I'm ready to go that route. I would look for a large surface mount solution if possible rather than using it or increasing it. I've been working on street projects for a long time and it's nice to have them in the tails and headlights at eye level to get more attention. People don't always see the beacon on the roof when driving through a construction site.
