They are fine, I have installed them on an electric scooter and they light up normally with the running light. Now that the base is rubber, time will tell.

I made a mistake in my order. I wanted them to emit orange light and by mistake I chose the white ones. They are very strong flashers and durable. I crashed with the scooter, it fell down and the flashers stayed in place and are still working.

So, the flashes are LED, and for those who don't know, machines that don't already have LEDs on them don't work well with LED flashes. Because LEDs operate with 1/3 of the current, they flash very quickly. You need a relay to slow them down. Also, you need an adapter; for each company, there’s one that costs a bit so they can fit into your flashes, unless your mechanic does some cutting and splicing. I've had them for over a year, they've been exposed to rain, dirt, pressure washers, everything, and they still work.

So far, after using it for 2 months, it is excellent. The effect worked properly and the brightness is satisfactory. A one-way street for their money.

Good evening, the flashers have rubber bases and are easily cut due to the sun that burns them and yellows the glass along with vibrations... out of the 4, 3 were in this condition...

Really nice flashlights and they actually work as flowing water (reversible light). Quite powerful light.
They were installed on a tracer 900. They went in the front without any effort or difficulty, for the back I needed to make 20-30 centimeters extensions for the plugs to reach under the seat but still without any serious difficulty. Really perfect!!! I hope they withstand time and weather conditions. Unfortunately, in the photos, the reversible flow cannot be seen, only where the photo was taken.
