Ok sights, could be a little brighter

Ok sights, could be a little brighter I thought, but in dark they are visible just tome stand out like some of the larger dots I have seen.  They do a very good job with normal light, much better than the stock SR9C sights.

BRIGHT, but not as bright as I hoped. They will do though.

Good but not as bright as we were hoping them to be. At times it makes it difficult to see if it's too dark.

These modules look great in my fog lights.  However, they aren't that bright.  The light coming out of my reflectors isn't as even or pure as the halogen bulbs these are meant to replace.  They're better than having no bulbs at all, but they may not be particularly helpful in improving your ability to see while driving.

I still like them, and run my car with them installed.

Don't dim quite as fluidly as daylight equivalent slim styles.

I bought these to put over my glasses while driving.  I just moved to Texas and it is crazy bright here.

I originally had some sunglasses like this but without the little windows on the side that I got at Walmart.  Those were better--they were slightly more comfortable and didn't look as dorky (the window on the side is both useless and unattractive).  However, I lost the other pair and wasn't able to find a replacement.

These work ok.  For my purposes I wish they didn't have windows on the side, were a little darker tinted, and were just a bit more comfy.  Having said that, they do fit and they do work as advertised.  I wouldn't be able to wear them all day because there a little less comfy, but they work well for the morning commute.

These were not as bright as the 6in ones you can buy for $1 at most places. They are just OK. I ended up not using them because of the lack of brightness.

Give a nice white light, but for all these are hyped up to be, they aren't much brighter on the road than standard bulbs.

They look very nice but the front sight does not really stand out that much. The orange ring is not too florescent and it doesn't glow super bright but it still looks good and will work fine.

Not quite as bright as I was hoping, but is still visible (Somewhat) in daylight. Does work very well at night.

Not bad for the price. I bought this light for the red light capability for walking to to a deer stand in the dark. The red light is really dim. Barely enough light to see what is in your hand. I will keep this light though and use it in the stand or blind to look in my pack and to hook up my fall arrest system since i think the brightness would be perfect for that limited range. It is a touch annoying that the strobe function can't be avoided when turning it off. The separate buttons for the white and red light is real handy though.

They are okay I guess. They didn't seem any brighter than the standard low beams at 55w, especially considering they are 45% brighter at 80W. I'm old school and hate the glaring bright blue headlights on the road. These are a nice white just wish they were brighter. A little disappointed in these "off road only" bulbs by Hella.

These were also hard to install, I recommend some oil on the oring. I guess they were a little oversize.

I'll run these until the first one burns out then try something else.

These lights work as they're supposed to but they aren't very bright.  I bought them to light up a medium size safe and I needed all three to just be able to see and it's not nearly as bright as I would like.  Oh well, they do work and the price was fair for what I got.

works as advertised. Bright but not very bright.

Harder to get the factory front site out that most of the videos show.  Install of Fire Sights was easy.  Visibility very nice.  Warning though: the rear site, at the lowest elevation may not go low enough to sight in, depending upon what sight picture you are lookiing for.

Decent light, not as bright as I hoped but is serviceable and priced right.
