This LED penlight is extremely valuable and portable. I use it mainly for HGN stimulus, but have practiced with it on the range at 25 yards and it will provide enough light to see a target if needed. The battery life is great as I have been on the initial set for over two years.

A must have light if you work night shift. Battery life is awesome.

I have one of these that came with my ticket board and I love it. Excellent for SFST

AKA DUI DETECTOR. Good for reading with too! Get two colors and you have a light show.

Great little lights...

I use one of these for HGN on DUI stops........ See the blue light.....

Good bright light from the manufacturers of quality lighting. LED's utilize very long battery life. I use mine on DUI stops also. I keep mine clipped to the pocket of my trauma plate & use a zipper on my uniform shirt for easy access. It's a little too long to clip in your pocket (but then, it probably wouldn't be as powerful a light with cutting down on a battery). I would have given it four stars but the clip slides along the penlight. I wish it was tack welded to the light instead of slipping up & down. It doesn't fall off, but it's just a little annoying.

Have issued hundreds of these little lights and carry it myself,

This is a great compact illumination device, I own the UV model and a red and blue standard models. These lights are excellent when it comes to saving your night vision, descretely signaling other officers, or scanning the area where you are walking. The red or blue model makes a good stylus for conducting HGN. The UV model is great for detecting forged documents or checking proof marks made with a UV pen. The batteries are a bit pricey but they last a long time. I have heard of a rare problem with the button springs going out, but I have oned my oldest stylus for 6 years now and have never had a problem. I highly reccommend this prouduct as a police accessory.

Had mine for about two years now...very practical little light. The only problem I have with it is that as the batteries wear down I find I have to smack it on stuff sometimes to get it to come on. Just bought a Stylus Pro (about $32) which is a little shorter and fatter but it's about 10 times brighter and it has battery-saving electronics. We'll see how that works over the next few months...

Great HGN light but also practical if you get in a bind and can't access your duty light!

Great light! No bigger than my pen but absolutely great for looking into small nooks and crannies - even in the daylight. In a bind, can replace your duty light
