Our Ultra Bright 24W 1200LM Wt21 4257 Amber LED W/ Built-in Resistors DRL and/or Turn Signal Light Bulbs, No hyper flash (2 Pieces) are amber colored type LED lights that cover 360 degrees to provide maximum output. Unlike other brands, with resistors on both the filament, we created a CANBUS LED that only has a built-in resistor only on the turn signal filament. Having a resistor on both the filament will lead to melting the housing or the LED falling apart in the housing. We even took it one step future to insure the longevity of the bulbs by adding a cooling fan. The fan only turns on when the turn signal is on, to reduce heat when resistor is on. Our Design protects the LED from being exposed to constant heat eliminating this issue. This assures no hyper-flashing or error codes. Our LED is designed to replace the factory incandescent bulb without the need to add extra resistors or parts.
Each LED is equipped with 54 SMD LEDs Amber Colored type LED lights 360 degrees to provide the max output. Each bulbs is 1200Lm, your turn signals will shine a lot brighter than the stock incandescent bulb.
You’ll be hard-pressed to find a brighter, more efficient LED bulb on the market! Designed here in the USA, these bulbs feature an impressive 54 amber color LED chip design.Installation
Difficulty Level: Beginner - Simple Installation for anyone.
Installation time is approximately 10 minutes. There is no need for slicing or complicated wiring. This light is a plug-n-play installation and operation.
Really wish ford would have done all LED bulbs from the factory. Ordered a set of these front turn signal bulbs and wow, they are bright and work great. No error codes or hyper flashing. Seem very well made too. Took about 20 mins for install. Have a set of the brake/turn bulbs on the way next.
These are amazing. They look and perform 100x better then the stock halogens. They really modernize the look of the XLT headlights. Ford should have made the turn signals LED with the rest of the headlight. This is a quick fix to that problem. No hyperflash as expected.
Better and Brighter than I expected. Very satisfied with the results. Definitely recommend these to anyone looking to upgrade from standard bulbs!
They are brighter than what I expected👍🏽
Customer service was top notch👍🏽
As advertised easy install great results ty
Ya gotta be blind not to see these .. I ❤️❤️'em
Bought some replacement LED bulbs for my Ford F150 to change out the halogen turn/brake bulbs. They were easy to install and visibility was much improved. The bulbs are very good quality and shipping was very quick. I give Underground Lighting two thumbs up!!
Look great. Works great. So far so good. Time will tell.
Exactly what I wanted! Love the very bright, crisp look of the LED blinker. Almost feel bad for the drivers opposite of me who have to see the flashing sun in their eyes while these are on. Super easy to install and truly plug and play. No hassle with splicing in resistors or hyper flash. Really happy with them so far!
