Did you purchase or install a set of LED Turn signals and now you have hyper flash? You need a pair of these load resistors! These resistors are spliced in parallel with the LED bulb to add extra electrical load (power dissipation) to the circuit, thus reducing blinking speed to normal rates. These are for turn signal blinker circuits ONLY.They are not designed to have current running through them for long periods of time, they will get EXTREMELY hot if you do so. This may cause fire or damage to surrounding components and the resistor itself. ONLY USE ON PULSED TURN SIGNAL SIGNAL / BLINKER CIRCUIT. NOT FOR parking or DRL USE. Features: 100% brand new and high quality. These load resistor can solve common SMD LED bulb turn signal problems. Will help to simulate the load and heat as traditional filament light bulbs. Can be used with vehicle turn signal light's LED conversion. Solve hyper flash or no blinking of turn signal. Each LED bulb installation requires one resistor connected in parellel. Fix blinker flash error, hyper or error flashing of LED turn signal, parking / driving running light or license plate light. It works as warning canceller, decoder, capacitor, or blinker rapid Flash Equalizer for LED light bulb such as 1156, 1157, 3156, 3157, 7440, 7443 or etc. Specifications: Material: Alloy Color: Gold & red Voltage: 12 V Resistance: 6 ohm Dimension(W * L): 15*50 mm/0.59*1.97 in Hole ID: 3 mm/0.12 in Package included: 10 * Load resistors 20 * T-Taps Friendly Reminder: PLEASE DO NOT MOUNT TO PLASTIC It Will Melt. Common Questions & Answers: Q: I installed the load resistors but they didn't make any difference, the LED lights are still flashing fast, what can I do? A:First, check that the wires are connected securely. Sometimes the connectors (t-shaped) may not have spliced the wires completely to establish contact with the copper wire. You will have to squeeze the connectors harder. If the load resistor works, the metal part will become warm in about 30 seconds and slowly getting hotter. Second, make sure to connect the wires correctly, especially for the bulbs that have 3 wires(e.g. 1157, 3157 & 7443). Q: I have changed front and back turn signal light to LED, how many load resistors should I need? A: EACH bulb needs 1 load resistor. You need 4 pcs of load resistors for 4 bulbs. Q: There are 3 wires coming from the light with color red, black and purple on the right and red, black, and green on the left. I have no idea which two wires to put the load resistors on. A: As to which colored wire is the correct one, it is simply a trial-and-error process. Normally, black is ground, red for parking light, the remaining colors should be the turn signal. Usually the turn signal light will differ on both sides to help distinguish them from parking lights. In your case, the two turn signal wires should be purple and green. Q: Would I need resistor in back up lights to control the flow of juice to leds? A:It is highly recommended that you add load resistors to all led lights. Q: I have changed my brake light to LED recently, but "bulb out" message appeared on dashboard. will the load resistors fix the problem? A: Yes. The load resistor is specifically designed to represent the same power-draw as a standard filament bulb so that the vehicle does not mistake the lower power draw of an LED bulb as a bulb that is burnt out or missing. Q: Why do my LED turn signals flash faster than my stock bulbs? A: This is known as "hyper flashing" or "rapid flashing". Since the wattage of LED bulb is much lower than stock filament bulb, the load resistor will draw out the residual wattage from circuit to LED bulb and thus the LED bulb will function like the stock filament bulb. Q: The load resistors are very hot, is it normal? A: Yes, the load resistor will become very hot under normal operation.Therefore, it is important to mount the load resistors to metal and do not install on/near painted surfaces, plastic or wires. THEY WILL MELT! Connection Instruction: One resistor is required for each LED turn signal bulb connect one wire to ground and the other wire to the turn/brake wire. You can use the T-taps so you don't have to cut your car's wiring. One load resistor is required for each signal bulb. Note: 1.Manual measurement, the size will have an error of 0.5-2mm，subject to actual size. 2.Due to the light and screen difference, the item's color may be slightly different from the pictures. 3.The colors may vary depending on the batch. 4.1cm≈0.39in. 5.The Load Resistors will get really hot as a working halogen bulb.Please mount them steadily onto metal surface and keep them off of any plastic parts to avoid plastic from melting down.
