Just Get SEALIGHT LEDs
These are much brighter than my halogens I replaced these with. I'm much more visible to other drivers. It DID require installing a decoder, but that was included with the bulbs and super easy to install so no loss of star on that. Regular flash interval, dual "filament," Im a believer in Sealight LEDs. They simply rock and at a fraction of the price! Hazards are bright allowing other drivers to spot me and avoid a hazardous situation. Wonderful function.

Very good lights at a very good price
The factory ones run hot and they kinda burn the headlight assembly, These are very cool temperature and much brighter

67% brighter bulbs, but, no différance in backup camera
The 2021 Chevy Colorado OEM Incandescent Toshiba 921 12v w16w got was around 1173 Lumens though the plastic Vs the SEALIGHT at around 2356 lumen That's about 67% brighter, although in my case the backup camera didn't change. (Pictures didn't really show much) I don't think this is the product's fault, I reason it's because the pickups backup taillights are so high, small, and not angled down. Pressing on the brake lights it up nice though. Will very likely be returning, It's not the "1300% Brighter" I was advertised, nor does it do what I wanted. I'll probably try a light bar on the bumper instead.

Fit great, bright.
Installed with resistors and work great. Bright. No flashing. Fit great and locked in. Won't buy another brand again.

They do not fit the Buick Encore sockets
Very nice bulbs but do not fit the 2013 Buick Encore sockets. Tried to plug them into the sockets and they would not go. Being a career Electrician, I wanted to use them so, I used a utility knife to remove the protruding tabs on each side knowing that I can't return them. My Encore requires two bulbs on each side in the front, only did this to one set of two that I ordered for the front. It worked, once the tabs were removed they fit very snug. Next problem, they "hyper flashed" (running lights worked correctly). They come with load resistors, very nice! Installed the resistors across the turn signal wires (not the running light wires) on both bulbs. Still got the "hyper flash" (running lights worked correctly) with the resistors installed. They were very bright if you want to live with the "hyper flash". No Canbus issue. Oh well, went out and bought new regular bulbs. Had to trim the tabs off the rear turn signal bulbs also to get them to fit in the sockets. They fit very snug. On the rear, they also "hyper flashed". Installed the included load resistors and this took care of the "hyper flash"! No Canbus problems. They are very bright and work correctly with the resistors. Used silicone to attach the resistors to the metal car body inside, next to the rear turn signal sockets. Side note: Even with the resistors installed on the rear LED bulbs; the front LED bulbs caused the rear to "hyper flash" even with the resistors installed on the front. The rear LED bulbs with the resistors work correctly with regular bulbs installed in the front. So, out of the three sets I ordered, I only have one set that I didn't touch. trimmed one and ruined for the front, trimmed one and used for the back with resistors and one wasn't touched. Live and learn!

Nice bright little LEDs. Installing is simple as removing the old bulb and inserting these.

Grandioso producto. Ultra bien acabado. Mi única queja es el tono blanco verdoso que tiene su luz... Sin embargo su brillantez y utilidad son incomparables.

アンバーと言うよりかは、純正ウェッジ球の 明るく少しオレンジ寄りって感じでした。 夕方でも周りが照らされてるって感じでした LED自体が少しゴツゴツしてるので 取り付け時、要注意です。 写真は、失敗例です。 バルブが引っ掛かり、ライト本体の中に落ちました。 こうなると、バンパーォ外してヘッドライトも外さないと、中に入ったバルブは取れません。
