If they do not work correctly, check all of your connections and the routing of your wiring, using the diagram above for reference. I agree with SgtWookie. From reading other topics regarding converting to led brake lughts, you normally need to add load resistors to the brake light so the ecu doesn't disable traction control and cruise control thinking there is a blown brake light. There are some after market lights that are not LEd and are really small and difficult to see especially during the day which can bring civil liability or traffic citations that I agree with enforcing. This video shows which wires you need to connect your load resistor to in order to restore cruise control to your vehicle. Introduction: How to Install Load Resistors for LED Turn Signal Lights. As long as they are DOT approved you shouldn't have any problems. 99 I do not know anyone who enforces it including myself. The speci- fications for most load resistors have 50 w capacity with a 6 ohm resistance. If you are trying to replace an existing incandescent bulb with LEDs, you definitely need a resistor. It could be looked at like for example a tractor trailer with 100 marker lights (chicken lights) if one is out, it’s a ticket in most states. If you've got (3) wires like this, you could simply have every other LED (or row of LEDs( wired through to the running light line, and the other rows wired to the brake wire for 1/2 the LEDs on during running operations, and all the LEDs on for braking. I've seen some aftermarket LED taillights that pulse and those are technically illegal (at least around here.) Copyright 1996-2017, Officer.com, Southcomm Business Media - Public Safety Interactive. If just one dot (led) is out you could and most likely get a ticket for a lighting equipment violation (depending on officer). Which after some research found out that I need the load resistors. Do you need Load Resistors for backup and brake/tail light LEDs. If in doubt, use a voltmeter or DMM to check wires. As of yet, the vehicle code hasn't caught up with them yet. This should work for '12 and '13 taillights. Tail lights to have running, stop and turn signal. I would replace the 180 ohm resistors with 270 ohm resistors. Every led in the tail lens better work.
