⭐ Warm Amber Glow with Reliable Performance

LEIDY CORNELIODecember 21, 2025✓ Verified purchase

These SEALIGHT 194 LED bulbs provide a nice warm amber (2700K) glow that looks great and improves visibility without being harsh. They fit perfectly as replacements for 194, 168, and 2825 bulbs, making them very versatile. Installation was quick and easy, and the LEDs light up instantly with consistent brightness. They feel well-made and durable, and the amber color adds a clean, classic look to the vehicle’s lighting. Overall, these LED bulbs are a solid upgrade if you want reliable performance, easy installation, and a warm amber tone. Very happy with the quality and would definitely recommend them. 💛 Read more

very very happy

Austin WadeJanuary 29, 2026✓ Verified purchase

Bought for my 2012 Honda Ridgeline these lights are amazing. The brightness is amazing. The upgrade value makes my truck looks so good and it fits everything in my truck besides my two front lights and the cab I would call them dome lights but fits the back dome lights that is something with my truck not with the lights. I highly recommend buying these and will be buying these again when they go out I be replaced every light in my truck with these so so happy the price is an amazing price got mine on sale and bought two packs.

Wish they sent more splice clips

Looks amazing as well as the packagingFebruary 17, 2026✓ Verified purchase

Great bulbs way brighter than my old halogen bulbs in my 2012 charger. Plug and play besides the splice clips that come with it. Had two snap during installation will trying to use my pliers to push it down. Really wish they would send spares just in case something like this happens. Read more

High quality dirty chip

Darius MaroszykFebruary 14, 2026✓ Verified purchase

Great quality led’s . Replaced traditional 194’s in my 2015 Ford Escape. Front side markers, parking light and license plate light. First thing first they provide much more light. Second, they not getting so hot like regular bulbs. With regular bulbs plastic sockets burn and falling apart after few years. LED doesn’t get that hot providing more white light. Additional benefit is that by swapping most of Buls in my car to LED’s ( including high, low beams, turn lights, tailgate) released some 300 wats from alternator and battery. Other very important point. Some month ago bought two 194 regular “long life” bulbs at store. Paid over $12 for two bulbs set. Led 194 10 pcs paid bit over $13. Calculation is simple. Really and honestly recommend these bulbs. Read more

Very bright

BhutchFebruary 6, 2026✓ Verified purchase

I bought these to replace the stock reverse bulbs in my 2012 focus. The vehicle has sat a lot over the past few years since I own a business and work from home 99% of the time. So when I started driving the vehicle more, I noticed a reverse light was out. Decided to give these a try though a lot of people said they didn’t fit. I’m convinced that most people that wrote reviews about installation issues don’t actually look at what they’re buying and match model numbers. These went in super easy. The passenger side didn’t work still but I swapped bulbs and determine that it’s a wiring issue, not a bulb issue. But even with one bulb in the back, it’s the first time in 13 years that my reverse lights have illuminated the objects behind me. My wife commented that the lights were visible from our living room when I backed into the drive as if they were headlights. I had no flashing or connectivity issues. They were compatible right out of the box. If one doesn’t work, flip the bulb around because some models do have polarity on the bulb. Read more

Bright (hyper flash resolved)

James E.March 30, 2026✓ Verified purchase

The media could not be loaded. Ordered these because Amazon said it would fit my 2016 F350. They do fit and work, but have the hyper flash when the turn signal is on. Added a resister as others suggested and yes, it gets hot, but I still have the hyper flash. Reached out to support and they are sending me something to fix it. Will update this post to 5 stars once resolved. These lights are bright and would like to keep them. UPDATE: Received the new smaller resisters from the manufacturer of the bulbs and they worked perfectly. I’ve included a pic of what they sent. Read more
