FAQ:
Q: What’s the advantage of a 921 reverse light bulb?
A: Their primary advantage against LEDs is the omnidirectional light output that the 921 reverse light housing is designed for.
Q: Which is the brightest reverse light on the market?
A: Introduction: The Lumenex Reverse Light Kit is the brightest LED Reverse Light Option on the market today! Coming in at a staggering 2100 Lumens of output, puts these nearly as bright as stock halogen headlights (which are around 2300 Lumens) So when our customers say these are like having headlights in your tail lights, we reply, Almost!
Q: What kind of reverse light bulb does a Tacoma use?
A: The 921 reverse light bulb is used in 2001-2017+ Tacomas as well as many other vehicles. A challenge for LEDs is the design of the bulb in relation to the housing it is placed in due to the directional nature of LED light.
Q: How are reverse light bulbs different from forward facing lights?
A: Reverse lights have no cut off horizon and emit light in all directions, therefore glare is not an issue like it is for forward facing lighting. I deliberately used bulbs that differed in design to see which bulb design did best. These are the OEM incandescent bulbs.
