ACR C-Strobe lifejacket light


Price as reviewed:


This is ACR’s strobe version of the C-Lite. It takes 2xAA batteries, and is activated with a
twist of the strobe housing. Like the C-Lite, it can be mounted either on the oral inflation tube or with a strap around a bladder.
You could potentially wave it in the air to attract attention, but you’d have to be confident you weren’t going to drop it. We found the strobe lights brighter than the C-lite but although bright, it had very short flashes. These were harder to pick out than some of the LED lights with their longer flashes.

We tested this light alongside 8 other incandescent, strobe and LED models. Read the reviews of other lifejacket lights on test.



You can replace the batteries yourself – but it’s not as visible as the LED lights with their longer flashes.
