Question:

Im thinking of changing to LED lights. 2010 Toyota Matrix XR . Do you need Load Resistors for backup and brake/tail light LEDs. What would be the cost from you for LEDs. Canadian Vehicle

When changing from incandescent or halogen type bulbs to LEDs, load resistors are required.

For the blinker circuits you can use load-resistors like the Putco LED Light Bulb Load-Resistors # DI34ZR to prevent hyperflashing of the blinkers. This kit includes two resistors and connectors for installing a pair of bulbs as turn signal lamps. Check out the installation instructions I have attached for part # DI34ZR.

I have also included a link to our exterior LED automobile lights for you to check out. Prices are available on these product pages or you can contact our helpful customer service representatives.

Hi i have replaced my standard tail lights with LEDs, also adding a load resister to the indicator to stop the hyper blinking, the problem i have accrued is the indicators are fine until i turn the lights on or touch the brake, as soon as either are done the indicators hyper flash, any ideas would be appreciated

What type of resistors? What rating? Maybe the resistor you used did not put enough load on the circuit. Take a look at the Diamond # DI34ZR resistors. They are rated 50 watts / 6 Ohm.
