Nine different light/* settings. Each unit has 3 aaa inside. You need to carry a small phillips screwdriver around with you if you want to change the batteries. Great to provide some light around the campsite at night.

Have a 39 foot motorhome towing a jeep. Luckily our tire pressure monitor alertes me with enough time to get off the road safely. Sticks well and plenty of lighting options.

This is not something you need to find out on the roadside in the rain.

The red light is bright (i have not tested it outdoors) and it gives you the option of flashing or glowing solid. The bulb dome is higher so if you mount them on a horizontal surface the bulb is far more visible.

Reviewer says kit is just what he needed for the road. Lasts much longer than any flare. Only complaint is the manufacturers packaging which was difficult to open. Bought a second batch.

The magnet is not very strong but then i assume its only meant to attach loosely. The packing is some of the worst i have seen.
