Review on 💡 Trueland H4 9003 LED Headlight Bulb: 10000LM Super Bright 6000K High Low Beam Kit (Pack of 2) - Anti Flickering, Canbus Decoder Included by Jason Adams

Choose this style (small upward reflector look for low beam leds) as other designs don't make a clear difference between low and high beam then without that what I do not want to live. They put out clear low and high beams on my 2008 Prius, although you may need to manually adjust the headlights a bit compared to the beams put out with halogens. They are likely to be more expensive than other upward facing LED bulbs. because of the built-in canbus module (which may not be needed on Prius 2 generation), but clearly good quality. The instructions are the same for all of their different LED headlight bulbs, without telling you how to orient them: in our case, the small reflectors should direct the light upwards. So just respect the high/low halogen bias. We had to reinstall them after figuring this out the hard way, so the product loses a few stars due to this omission in the instructions. We decided to cut a larger hole in the rubber boot that covers the hole in the back of the headlight housing, those big bulbs; Hopefully these modified boots don't interfere with the lamp's cooling process much. I will be changing this review in a year or more to let you know if they are still working.
