These little torches are amazing, only 60 x 45 x 20mm in size and less than 50grams. They are magnetic so can be stuck onto the side of the vehicle or anywhere else. There is a clip out stand and a carabiner latch to be hooked on your keys. I use them for everything as they are so handy and the battery lasts for ages.
Push the button one and it's on bright, 2nd push and its medium brightness and a 3rd push it flashes.
They charge via USB C
Specs are 6Watts, 500MAh battery
