Description
The Hi-Viz GLT178 Litewave is a front and rear target sight set built to make your Glock's iron sights easier to pick up, especially outdoors. It comes set up with a green fiber-optic front and a red fiber-optic rear, giving you a fast, high-contrast sight picture that guides your eye straight to the front post. Both bodies are all-steel, so they hold up to real range use and years of holster wear.
What Makes the GLT178 Litewave Different
The standout feature here is the interchangeable LitePipe system. The front sight ships with green, red, and white LitePipes, while the rear includes green, red, and black options. That lets you build a sight combo that works for your eyes and your lighting, whether that's a green front over a black rear for a clean target setup or a red-on-red pairing if that's what jumps out fastest for you. Front LitePipe diameter is 0.090 inch and the rear is 0.078 inch, and both are user-replaceable when a pipe eventually wears out.
Fitment and Sizing for the Litewave Set
This set is designed for Glock models chambered in 9mm, .40 S&W, and .357 SIG, and it does not fit the slim-frame 42, 43, 43X, and 48. The front sight measures 0.215 inch tall by 0.120 inch wide, and the rear stands 0.224 inch tall with a 0.140 inch notch width. Installation is straightforward for anyone comfortable with a sight pusher and the correct front sight tool, though a gunsmith can handle it quickly if you'd rather not tackle it yourself.
Why Folks Reach for These Sights
These are a favorite among target and range shooters, and they're a popular pick for anyone whose eyes have a harder time focusing on plain black factory sights. The fiber optic glows brightest in daylight, so if you spend most of your trigger time at an outdoor range or in the sun, this set earns its keep. Hi-Viz also backs the product with a limited lifetime warranty against manufacturing defects.

Frequently Asked Questions
Which Glock models does the GLT178 Litewave sight set fit?
It fits all standard Glock models chambered in 9mm, .40 S&W, and .357 SIG. It does not fit the slim-frame Glock 42, 43, 43X, or 48. It's also not made for MOS or optic-cut slides, so check your model before ordering.
Can I change the fiber optic colors on this Litewave set?
Yes, that's one of the best parts. The front sight includes green, red, and white LitePipes and the rear includes green, red, and black, so you can mix and match to find the contrast your eyes pick up fastest. The pipes are user-replaceable, so you can swap them again down the road.
Are these Hi-Viz sights good for low-light or night use?
These are fiber-optic sights, so they shine brightest in daylight and outdoor conditions where they can gather ambient light. They are not tritium night sights and won't glow in the dark on their own. If you want visibility in total darkness, look at the Litewave H3 series, which adds tritium.
How hard is the GLT178 sight set to install?
For anyone with a sight pusher and the correct Glock front sight tool, installation is a straightforward job. If you don't have the tools or aren't comfortable working on your slide, a gunsmith can knock it out in a few minutes. Take your time seating the rear in the dovetail to avoid marring the finish.
