Switchback: white running light, flashes amber when you signal. The white running light turns off while the amber blinker is on.

Fan-cooled LED blinkers. Bright, attention-grabbing and built to last, for trucks and cars.

Why LumX-FC

  • Industry-unique fan cooling. A built-in fan keeps the high-power LEDs cool, even during long use, so they stay bright and last longer.
  • No hyper-flash. Advanced CANbus means they work properly in every compatible socket, whether as turn signals, brake lights or hazards.
  • Clean OEM look. Colored bulbs can tint your reflector housing and look tacky. Ours have no reflective colors and are chrome plated, so they blend into the housing, arguably better than the stock bulb.
  • Easy install. Plug and play, built to last.
  • Quantity: 2 bulbs
  • Fits sizes: 3157, 3057, 3155, 3156, 3357, 3457, 4057, 4157
  • Power: 15W
  • CANbus: Fully integrated (works on 95% of vehicles)
  • Use: Signal, marker, brake, tail
  • Length: 2.32 in (59 mm)
  • Diameter: 0.79 in (20 mm)
  • Output: 250 lumens white, 1,460 lumens amber

If you're looking for top of line? These are them!

Yes thier spendy but the quality of them is amazing! I've only been running them for a week now so hopefully they'll continue to impress me but as of now, I'm impressed! They are extremely bright! They have nice amber color to them, I have waisted a lot of money on leds that had a light yellow color to them. These are not that! I'll be ordering the red ones for the rear soon

Wish it was plug and play, like the headlights, instead of having to play with set screws

Work great

No complaints. Easy to install and customer service was very helpful with an exchange. I did all the rear lights in my 2002 Duramax and they look great.

Works great

So far they work excellent, installation was a breeze. I’ve only had them in a few months, so I’ll see how long they will last.

Great Product and service.

I have replaced every light on my truck with bulbs from this company and have been more than satisfied. I previously tried some cheaper versions from one of their competitors with less than satisfactory results. I could not be more pleased with the quality of the products and the customer service from Diesel LED's

Best & Brightest

Perfect bulb for your front turn signals. Running light until the turn signal is activated, then it's an amber turn signal light. Highly recommend!

Bright, Durable, and Easy to Install – Highly Recommended!

I recently purchased the LUMX-FC Amber Blinker (3157) from Dieselleds, and I couldn’t be happier with the product. The quality and brightness of these blinkers are outstanding, providing excellent visibility even in bright daylight conditions. Installation was a breeze, and they fit perfectly into my 1999 Ford F250.

What stands out the most is the durability and performance—there’s no flicker or delay, and the amber color is vibrant and consistent. It’s clear that a lot of thought went into the design and build of these bulbs. They’ve definitely enhanced the safety and appearance of my vehicle.

Dieselleds also provided exceptional service, ensuring fast shipping and great communication throughout the process. I highly recommend the LUMX-FC Amber Blinker to anyone looking for reliable, high-quality replacement bulbs. I’ll definitely be shopping here again for my lighting needs!

Switchbacks don't switch

I bought the switchbacks because the description says they are white when driving lights and turn amber when turn signals. They're just amber and brighter amber, they don't switch to white.

Anthony Maszgay (Carnegie, US)

Lights worked perfectly

J
Jeffrey Kniffin (Belmar, US)
Holy Bright Batman

These are really eye catching. The reverse lights are obviously bright because they're clear and you see them at night only really, but the amber blinkers are bright even in the daylight. I had a friend following me to another friend's house, and he asked me, " Why are your turn signal lights so bright?!"

These LEDS are AMAZING!

I had a previous version of these LEDS from Dieselleds, and I must say, the new version (LUMX-FC) is amazing! They are brighter than the older version, and all I can say is WOW! Thanks Dieselleds for such an amazing product!
