Quick question, yesterday i installed two red whelen vertex LAWs in my DRLs, i have them all wired up and flash patterned synced together (so they are on the same pattern) Now the question is, how do i get them to alternate, like instead of them being on the same pattern and flashing together, how do i get them to be on the same pattern but flash alternating ? Is this possible ? Thanks for all the help.

Yes it is possible... You just have to advance the flash pattern forward on one fo the lightheads to it is on the "B" side of the flash pattern... Each syncable flash pattern on a Whelen lighthead has the "A" and "B" side. If both heads are on "A" or "B" they will flash together, if one is on "A" and the other is on "B" they will alternate...

Just tap the power select wire (usually white/violet) white to power on one side on one lighthead, that will change the mode on the light. That light will then alternate with the other.
