Muskegon, MI. Apr 26, 2015. #4. For some reason I thought I responded to this unless there is a duplicate thread. Turn signals will flash rapidly if you do not use a load resistor and apparently the passenger side brake light is looked at for cruise control. So if you upgrade your bulbs to LED you will have to put load resistors on the main It's not a matter of CANBUS or not. LED bulbs have a lower resistance than regular filament bulbs. The JK/U is designed to hyperflash and display a message if a bulb fails and it's resistance changes. In order for an LED bulb to work, the add-on resistor is typically needed to compensate for the LED's lower resistance. Where a series circuit receives the same current to each LED, a parallel circuit receives the same voltage to each LED and the total current to each LED is the total current output of the driver divided by the number of parallel LEDs. Again, don’t worry, here we will see how to wire a parallel LED circuit and that should help tie the ideas SEALIGHT 9007/HB5 LED Bulbs, 24000LM 800% Brighter Dual Hi/Lo Beam LED Bulbs, 6000K Daylight White Halogen Replacement L2 LED Bulb with Cooling Fan, Plug-N-Play LED Fog Light Bulbs, Pack of 2 4.4 out of 5 stars 4,299 This is usually solved by installing a driver on the headlights that are able to support the steady voltage needed by the LED headlight. It’s possible that the wiring on the car is not able to deliver the needed stable current, so a driver will shoulder that burden. If the flickering persists, double check the relays, switches, and other 2009 - 2014 Ford F150 - LEDs - Do Not Install Load Resistors for Hyperflashing! - I am not sure if this is posted here anywhere or not so I will post. (Mods feel free to merge or remove its this is a dupe.) I recently went down the road a full LED conversion on my 2011 F150 XLT. From the get go I was against the idea 408P. 344 posts · Joined 2011. #10 · Jun 17, 2011. It all depends on what you buy.If you only get LED replacemet bulbs, you probably need resistors. If you buy an Tail light LED upgrade kit they are usually included. As far as the kits go, the cheaper ones have to be hardwired into your original wiring. iJDMTOY (1) 3-Pin CF14 EP35 Electronic LED Flasher Relay As LED Related Turn Signal Bulbs Hyper Flash Fix. $9.49. Uriveusa 12V Car Add-A-Circuit Fuse TAP Adapter Fuse Holder with 10A, 20A Fuse [Upgraded Fuses] - (2 Pack) $9.98. The flasher needs a lot of current going through it to make it flash. Since LED lights draw much less current than incandescent you have 2 choices - buy an LED flasher or add resistors at the turn signals to burn more current. Depending on how the bike is wired you might need resistors on multiple lights. Do I need 4 load resistors or 2. Solution for Rapid Signal Flashing on Utility Bed with LED Lights; Do Putco Ceramic Load Resistors P230004C-2 Get Hotter than the load resistor should be wired from + to - across the 2 wires for the light, the reason it flashes fast is because it detects a light out due the the low resistance the LED presents, when you put the resistor in parallel with the LED it pumps the load high enough to read as a light bulb. 2015 Chevy Silverado 2500 HD 6.6L LML.
