Correcting Hyperflashing After Installation LED Taillights on 2004 Dodge Ram 3500

Question

Question:

When I hit the brake, it slowly blinker flashes. Also, hyper flashes like a strobe when I hit the brake. Im installing LED lights. Do you have a cold diagram to wire the 4 wire into 3 and stop the hyperflash?

In order to stop your turn signals and brake lights from hyperflashing with your LED taillights, you will want to install LED Light Bulb Load-Resistors on the turn light and brake signal wires.

Hyperflashing is a common issue when changing incandescent bulbs to LEDs. One of my fellow Experts put LEDs on his Dodge 2500 and ran into the same issue. He used the #DI34ZR Load-Resistors on his truck to solve the hyperflasing issue. I've attached an installation video of these load resistors on a vehicle with separate wiring for you.

Wiring a 4-wire system to a 3-wire will not prevent the hyperflashing, but the load resistors will take care of this issue.

Hi, I installed a flatbed on my 2005 Dodge Ram 1500 which has LED lights compared to the front incandescent and the turn signal were hyper flashing. I brought it back to the place that installed and they tried wiring in resistors but didn't work. The only thing they could get to work was get the old light set from my truck bed and wire them back in and zip tie them up under the flatbed. I'm not so fond of that idea, so wondering if there is a different way to make this work. Is there a plug and play resistor i can use to make it think the old lights are still in or what do i need to do to eliminate the old lights underneath the flatbed. Thanks

Adding resistors like # P230004A-2 in-line with the turn signal circuits is the solution here, but you mentioned that the installers already tried this? I'm curious as to why this didn't resolve the issue. Do you know what specific type they used?

Ive got an 03 dodge 2500. I bought a new led tail light assembly and also changed the front turn lights in the headlights also. Now heres my problem. I wired up the resistors to the turn light wire and ground on every light. When i turned the blinker on everything was working fine. No more hyper flash. Turn right blinker on both front and back working. Turned left blinker on both front and back working. Hit the brakes they worked. Turn running lights on they all worked. So instarted putting the tail lights back in and decided to check one more time. Well this time nothing worked other then my running lights. The left blinker barely even lighting up. The right blinker is hyper flashing. Any ideas about what could be wrong. Im trying to get some answers before cutting everything to redo it. Any ideas

So when everything initially worked - what was the actual difference? Were the new tail lights just not actually secured yet to the truck, and once the assemblies were mounted the issues arose? If so, make sure the grounds on the new tail lights are securely attached - it could be a weak ground causing this. Let me know what you find and we can keep troubleshooting.

We wired everything up checked to make sure everything worked before putting the assembly back into truck. Then bolted everything back on. Checked all lights again. Left turn right turn. Brakes lights running lights. They all worked. Started to check again. Hit the left turn and it wasnt working@ChrisR

@Joshua Thanks for the additional info. This is quite strange, since it sounds like everything worked perfectly after the initial install and wiring. I'm not sure what would have quickly changed this. Did the grounds come loose after bolting the assemblies back into place on the truck? I would start by checking this.

Answer 1

You will wire a load resistor into the wiring of each light socket that has an LED bulb and flashes. So basically you will need to wire a load resistor into any bulb that blinks or has a dual intensity feature that lights up when the brakes,…

Each bulb should have a power wire and a ground wire. As you can see in the diagram I provided, one lead of the resistor is tapped into the power wire, and the other lead of the resistor can either ground to the vehicle or tap into the ground wire…

What you are describing can happen on vehicles when LED lights are installed but there is an easy fix. The problem is that the low power draw of LED lights can make the vehicle computer think that there is a bulb out because there isn't enough…

From what I could find it looks like your 122R (red) and 122Y (amber) lights measure 3.75" x 1.70" x .81". We don't have any replacement lense directly for the GLO-BRITE lights but we do have some similar lights that you could use…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…
