using the sticky in the top of this forum you can search to see if other threads exists on a topic that you want an answer on. :-)

For example:

Will result in a pile of results on this topic.

You need either a load resister or your need Leds that have resistive loads built into them that mimic an element of a bulb to have your high beams function again. As phattyduck stated.

LED bulbs in certain light circuits will cause unintended side effects and I am wondering if they can cause some circuits fuses not to work properly. As their have been instances of melt downs without the fuses blowing due to the nature of the LED being a diode and stop current from flowing or only one direction in 3rd gen 4 runners.
