At first glance, this LED taillight looks somewhat unfamiliar. This comes from the colorless plastic masking on the LED bulb. Only the reflector (the bottom of the screen) is red. The LED bulb itself is lit in red: that plastic is above colorless but has a practical reason. The clear plastic, the light can then enter undiminished intensity outwards.
Please note: the backlight does not have an on / off switch.
I am very pleased with this tail light, I therefore especially thanks to the little price a strong buy recommendation.
