Description
The Hi-Viz LiteWave H3 is one of those upgrades that pays for itself the first time you draw in low light and instantly find your front sight. It pairs true H3 tritium with Hi-Viz's own LitePipe fiber-optic technology, giving you a sight that lights up in daylight and glows on its own after dark. The front post carries a green tritium dot wrapped in a bright white outline ring, while the rear runs an orange fiber-optic LitePipe for a clean three-dot picture with plenty of contrast between the two colors.
What the LiteWave H3 Brings to Your Glock
The standout here is speed of acquisition. That white ring around the green front dot makes it dead simple to snap your eye to the front sight and get a hard focus, which is exactly what you want when things happen fast. The orange rear keeps the two planes visually separate so you're not staring at three identical dots trying to sort out alignment. During the day the fiber pipes gather ambient light and pop, and once the sun drops the tritium takes over for genuine 24-hour visibility.
Built Tough and Sized Right
This set is all-steel from front to rear, so it holds up to hard use, repeated draws from a Kydex holster, and years of carry. Hi-Viz builds these to factory sight height, which means they duplicate your stock Glock sight geometry and keep working with the holsters and accessories you already own. No surprises on point of aim, no fighting your rig.
Fitment for the LiteWave H3 GLN425
This GLN425 configuration fits all-generation Glock models chambered in 9mm, .40 S&W, and .357 SIG, including popular guns like the 17, 19, 26, 34, and their kin. It does not fit the slimline 42, 43, 43X, or 48, which use a different sight set. Installation calls for a proper sight pusher and press, so unless you've got the tools and know-how, it's worth having a gunsmith set them in the dovetails for you. Hi-Viz backs the tritium with a 12-year warranty against loss of illumination.

Frequently Asked Questions
Which Glock models does the LiteWave H3 GLN425 fit?
This set fits all-generation Glock pistols chambered in 9mm, .40 S&W, and .357 SIG, covering popular models like the 17, 19, 26, 27, 34, and more. It does not fit the slimline 42, 43, 43X, or 48, which take a different sight set. If you run one of those slim guns, you'll want the dedicated version for that frame.
Are both the front and rear sights illuminated at night?
The green tritium front dot glows on its own in the dark for true 24-hour visibility. The rear uses an orange fiber-optic LitePipe that gathers ambient light during the day for a bright, high-contrast three-dot picture. In daylight the fiber pipes pop, and after dark the tritium keeps your front sight visible.
Can I install the LiteWave H3 sights myself?
These press into the dovetail cuts on your slide and really need a proper sight pusher or press to install correctly. If you've got the right tools and some experience, you can do it at home, but many folks have a gunsmith set them for a clean, secure fit. Doing it right protects the sights and keeps your point of aim on track.
Will these sights still work with my existing holster?
Yes. Hi-Viz builds the LiteWave H3 to factory Glock sight height, so they duplicate the geometry of your stock sights. That means your current holsters and accessories should keep working just like before.
