Review on ALLA Lighting H8 H9 H11 LED Switchback Fog Lights: High & Low Beam Conversion Kits, DRL, Dual Color 6000K White/3200K Yellow - 12V H16 H8LL H11LL H965W, Super Bright 8000 Lumens by Victor Olsen

Conclusion: They are NOT synced. The brightness of the headlights is amazing and installing it on the BMW i3 was a breeze. . The value can be reciprocated for all, I considered it 5 stars. However, blown material will NOT be synced. You talk about switching the light (on/off (0.5s)/on) for 0.5 seconds and you get yellow lights. So expect them to come back as 6000K after more than a second. No; That sucks. Example: Country road (2 paved lanes, 65 mph). Night driving, there may be 4-5 oncoming cars for 5 miles. Just drove out of town, the bright lights were out for a good 10 minutes. When I start driving on a country road, I went to the high beam, where I installed them and both worked at 6000. After 1 minute (high beam) I have an oncoming car, I only switch to low beam. About 30 seconds later, an oncoming car drives by and I turn the high beams back on. The lighting on the driver's side is now 3000K and the passenger's side is 6000K. I'm not sure how long it will take for the bulbs to reset/reset to default at 6000K. However, this is MUCH longer than a simple 1/2 second delay between on/off/on. Maybe my lightbulb on the driver's side is just stupidly plugged in. However, the passenger side still seems to toggle 6000/3000/6000/3000 even with an OFF delay of >10 seconds after the last 6000K off. They return. as I will not make BMW and/or myself look stupid for leaving them fitted.
