Resistors work just fine but doing this is much cleaner!

[@brianz4948]

Worked great, so much easier than installing resistors

[@kevinjost8588]

Worked great, fixed my hyper flash after i did the drl mod and installed switchbacks. My blinkers are a bit slower than stock, maybe its the difference in relays? Both switchback turn signals function properly. When I turn on flashers, the switchback bulbs go white for a split second then flash amber and repeat. Not terrible as it only does this with the emergency flashers on.

I wish vehicles still had the flasher units, instead it controlled by the BCM. I didn't have to pop the knee bolster off, I just reached quite far back and changed it by feel.

I've just replaced just all the bulbs in the rear and third rear tail light with led lights and got the hyperflashing going on and it's super annoying but I also put in hid(8000k)front lights and I like your front switch backs I think you called them but I also really like the led running lights that they got out now along with the led strips for the running lights it would look nice but putting a ton of money in a truck that's this old.... idk about that idea I mean I got a aydio system but all that like the speakers and amplifiers all can be pulled back out pretty quickly and I really want to replace the 160 amp alt to a 400 amp with possible lithium battery cells or headway cells its a type of lithium that can be charged at 14.8 volts and possible delete the front battery or getting a xs lithium and just save my alternator and battery for when I want to get another vehicle it all can be pulled out my truck is 170k but is in the rust belt but thanks for the video it's very helpful n wondering if it would help me also?

[@ZPTVChannel]

I feel you about putting the money into an old truck lol mines at 310,xxx miles and I’ve put over a couple grand into it already and planning on doing a lot more lol it really just depends on you I’m the type that doesn’t like to throw something away and if I can make something old new again I like to do that stuff. But as far as the hyper flashing the relay I got should fix that problem. Also living in the rust belt with these trucks involves a lot of maintenance thankfully I’m in Tennessee so not too much exposure to salt and stuff like that. But 170k miles your trucks still young as long as the rust isn’t too bad I’d say it’s worth building!

[@dominicr2733]

brotha. finishin up a welding bed over here i got the bed incomplete but there was a nice 56” cutout for a led turn signal bar. the 4 running led lights i put on each side work fine the led bar acts very erratic

[@dominicr2733]

with lights on it mostly works fine sometimes if u push the blinker level a little too hard or soft the rear blinker wont work. sometimes u flip the blinker and it wont work til u pump the breaks a little. u think this might be my issue? my blinker in the truck also flashes a little fast

[@ZPTVChannel]

Very possible! The stock flasher relays freak out when leds are installed and they also do some wild things when the flashers are going bad as well. My left blinker would do anything about 90% of the time and once I added leds they hyper flashed like crazy but after I installed the new Novita relay everything works perfectly!

What if your dash turn signal arrows stay on, but you have no turn signals at all. If I turn the lights completely off I can turn on the hazards but they flash really fast.

After putting led turn signals my rear brake lights do not light up unless I’m using a turn signal. Do you have any suggestions??

[@ZPTVChannel]

Most likely a blown fuse. But it could be a bad brake light switch or a faulty flasher relay. I’d start at the fuse though.

[@ZPTVChannel]

Also make sure the leds aren’t in backwards most leds are polarity sensitive try pulling them out, flipping them 180 degrees and putting them back in.

[@Demolitiondude]

I got the weird problem of my right turn signal on the dash is hyper fast but left turn signal isn't.

Not yet. That's on my to do list.

Will this fix led running lights that are flashing? Not the blinker just the regular running lights that stay on because this would be easier than resistors

Try swapping them and see if the other bulb starts doing it. If the same bulb is still doing it in the other side it’s probably an issue with the bulb.
