there are two brass screw holes on each side of the lens, what is that for? also, 8 red lights on the side of lens 1 is not lit - t

The screws are to tighten the angle of the camera once you set it up as u need. The red lights are the undated a for night vision. They work as needed depending on the light around it.

The lights are infrared so the are on but you can't see them. The brass screws are to lock it in position once you have the angle of the camera set.

There is a lock/button on the side of the barrel. Don't push or press in this button. Instead, push it along the barrel, i.e. the direction along the lens.

The lenses are red. Unless they have made a change in the bulbs inside the light assemblies since I bought these bags last year you should plan on having to remove the entire light assembly to get the 5 watt bulbs out since they will burn out very quickly. The light assemblies snap in and can be removed with a little patience and a small flat blade screw driver. I replaced the 5 watt bulbs with 10 watt ones available at any auto parts store. While I had the units out I used a Dremel tool with a sanding drum to enlarge the hole in the chrome reflectors so I could change the bulbs in the future without having to remove the entire light assemblies. These bags are well worth the little bit of money they cost but keep in mind they are manufactured in China and like most Chinese products, inferior engineering is a built in feature you're going to have to deal with.

The one that I have leaves a black ring on the outer edges of the picture. It is something inside of the telescopic lens that has the defect. However, I did only pay $12 for it and you get what you pay for.

I'm using them with a red lens for the rear lights of my motorcycle, the clear portion that illuminates the licence plate appears to be bright white

I presume you mean the stop-screw that can be seen at 9 O'Clock in the image here (since the main lens fittings are all bayonet fittings). I think it's either 1mm 0.25 pitch or 0.8mm 0.2 ptich.

You must look at the thread size of your lens and not just what lens it is. These are two different things.

Don't know. Did you adjust horizontally, the lens housing separates in the middle.

There should be a switch on the cord with an on/off button. Or try turning the lens.

I really don't know. However, after looking at it much closer it appears that the lens is either 'glued' or 'screwed' to the chip. The assembly is very fragile, i.e., one wire neede to be re-soldered...I don't want to mess with it anymore. If you would like I can send you a jpeg close-up for your perusal.

Streamlight has a lifetime guarantee. When I sent mine back a few years ago they replaced a problematic part. I would assume that the lens is covered. While it is there they may updated other parts of the light.

There is a button on the side of the-adapter, you need to pull out or push in to un mount the lens

My lights have glass lenses and "magnesium alloy" bodies. they are joined together in one unit.

There may be film covering the lense or it may have been a low light situation otherwise try a different computer

You can mount them either way. If the light is upside down from the way you want it to be, just unscrew the lens, turn it over and put it back together the way you want.

My best guess is that it's a grey market lens. Several of those companies sell them at very low prices. Be careful as they don't have US warranties. A quick google of the business name will usually tell you what you need. A good price just as long as you never need service. If you do, you're screwed.

There is a lock somewhere outside the lens near the body. This might prevent you from changing the focal length.
