They were the wrong bulbs. After I asked through messenger if I was purchasing the correct bulbs for my 2017 Tahoe premier. I’m so disappointed
9006/HB4 LED Headlight Bulb Forward High Beam and Low Beam 12000LM Per Set, Mini Size HB4 Wireless
Brighter then the regular H7 bulb, when not using lights during the day I’m getting Canbus Error left and right bulb out on dash. I got in contact with customer service and they sent the device to correct it for free. But there is no way the device can be attached to LED bulb cause on my vehicle the actual socket holds the bulb into the bulb clip which holds the LED bulb in place. The only way that I can use the device if some other clip is available using the light socket, Just to hold the LED in place to insert into headlight. Guess I have error until lights come on automatically while driving at night. Overall good price easy fit, 100% more brightness. Definitely recommend.
These new LED bulbs are super bright there is no way other drivers cannot see when you put your turn signal on. With the CANBUS resistor I have no hyper flash on my 2019 Subaru Forester. Glad to have found such a great addition to my car.
Packaging, construction and feel of the bulbs is very good. The overall brightness is good as well, not too bright and blinding for traffic. The bulbs themselves, however, aren't adjustable. I was lucky to still have a good enough beam pattern by not having to keep them in a 3 to 9 o'clock position but most vehicles will require adjustment. Otherwise the pattern and spread is good (i.e does not blind oncoming traffic), not sure about longevity as it's only been a few days but the overall quality is decent. Would recommend.
