Let’s talk “stock”…
More specifically, stock blinker bulbs.
The minimum brightness allowed on road-worthy vehicles is a measly 80 lumens. If you’ve ever bought light upgrades for your car, truck or SUV in the past… You know that is downright dim.
In fact, that’s what we at LumX call… Practically invisible.

Reasons why you need to upgrade your stock blinkers:

  • You face a higher chance of accidents with slow and dim blinker lights
  • The “normal” bulb lifespan of 250 hours is less than 15,000 miles
  • Aftermarket bulbs simply “pop” out on the road and make your vehicle modern
  • Better light distribution and visibility in all situations, day and night

Your Blinker Advantage:
LumX-PRO Technology

Seamless Installation

Most other LED blinkers use resistors, requiring you to rewire your blinkers during installation, but we take a different approach.

LumX-PRO  lights are designed to look and behave like stock blinkers (but 5X brighter on average), with IN-LINE resistors, making them 100% error-proof. And a simple twist in application. Installing these are practically as simple as replacing your blinker with another stock bulb.

Superior Color & Illumination

Instead of an ugly tacky looking bulb, with lots of cheap looking LED chips plastered all around it. We've taken a minimalist design, that simultaneously improves the reflection of the light limited from the bulb. 

LumX-PRO  lights boast an incredible 950 Lumens, which is immediately available as soon as you turn on the blinker. Normal blinkers take up to 1 second to illuminate after turning on the blinker; LumX-PRO is instant.

Plus: LumX-PRO LEDs are true Amber, meaning you’ll have a bright Amber bulb in your clear reflective lens, making your blinkers shockingly pure, modern amber in hue compared to everyone else on the road.

Technological Resilience

You buy LED bulbs for advanced service life and brightness, but so many LEDs burn out far before they should. Why? Overheating. Most companies do nothing to address this.

LumX-PRO is different. With the LumX-PRO set, the LEDs are embedded in in a machine milled piece of aluminum, effectively attaching the LEDs to the large heat sink on the back of the bulb. Ensuring the LED chips are effectively cooled at all times. Effective cooling is KEY to a long lasting LED bulb. We've taken the same technology companies use to cool their headlights, improved it. Then applied it to our blinkers.

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!

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
