Hyperflash Turn Signals - prevention

[rdhogg]

I had HID's installed on my 2013 Tahoe and while they were doing it I had them put in CREE LED switch/back turn signals in the front with a load resister to prevent the hyperflash. Everything is working great.
Question is now I am going to put 3157 Morimoto X-VF LED's in the rear signals, but I am not sure what is correct load resister to put in. I have watched a couple of Youtubes and they used 50W 6ohm, 50w 5ohm, 40w 7.5ohm. No one recommended what was the best, so I turn to the best of the best for advise. What say you !

I believe that any of those resistors would work, as there is very little difference in their ohm resistance.

led flasher should also be way to go.

Thanks Joseph. The Morimoto one is 40w 7.5 ohm

Thanks, do you think because I already have a load resistor on the front switch backs that there would be no problem with adding a LED flasher

I have hyperflash with my LED directional signals, but I did not install a resistor. I believe that the hyperflash actually makes the directional signal more visible to other motorists on the road, which is the whole point of having and using directional signals in the first place. I have heard, however, that hyperflash in not legal in some states.

GMT900 platform doesn't have a flasher that can be changed like the older platforms... the flash rate is controlled by the BCM.

The higher the wattage rating of the resistor, the cooler they will stay when being used.

the hyperflash can be disabled via BCM tune..


for the both front and rear if anyone says other wise I cite the Cadillac Escalade

The install is completed, I went with the Morimoto 40w 7.5 resisters instead of a LED flasher, I used Sylvania 7440 ZEVO's for backup lights (much brighter that GTR, Morimoto and GREE lights because the ZEVO LED is aimed back towards the reflector in the backup light socket. The 2013 Tahoe's have two tail lights on each side but only the bottom lights has the turn signal so in wiring the resister to that socket use the top row of wires that has YELLOW , BROWN and BLACK wires. The YELLOW and BLACK in that row are the ones you need to tap into for the resister , the bottom row of that socket are the BROWN and BLACK wires that go to the other tail light in that tail light assembly and if you tap into those you will not correct the Hyperflashing... I am pleased with the results and with the addition of the Rough Country slimline off-road LEDs used as back-up supplemental I can now see where the hell I am backing.
