Tritium (symbol T or 3H) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called triton) contains one proton and two neutrons, whereas the nucleus of protium (the most abundant hydrogen isotope) contains no neutrons. It is a gas (T2 or 3H2) at standard temperature and pressure. Tritium combines with oxygen to form a liquid called tritiated water T2O or partially tritiated THO.
Tritium is radioactive with a half-life of 12.32 years. It decays into helium-3 by the reaction releasing 18.6 keV of energy. The electron has an average kinetic energy of 5.7 keV, while the remaining energy is carried off undetectably by the electron antineutrino. The low-energy beta radiation from tritium cannot penetrate human skin, so tritium is only dangerous if inhaled or ingested. Its low energy also creates difficulty detecting tritium labelled compounds except by using liquid scintillation counting.
Basically its radioactive so it glows in the dark, ie input into switches so they glow w/o electricty.

The tritium in the vials is 100% safe and the radiation from them is next to nothing. At least if you installed some of these vials, you won't have to replace LEDs or bulbs for at least 12 years

Well, I've considered adding a light near my door locks to illuminate them at night and maybe mounting one or two of them under the door handle. Being I have a black truck, at times in an area without a full moon or street lights, I will be fumbling to find the door handle and the lock. For the lock, I wish I knew of a way to make the type of lock this old POS Mercury station wagon of my parents had. When you lifted up on the door handle, it illuminated an area about the key hole. Wiring can be a pain at times, so why not add a light that never goes out and has no impact on your electrical system :)

NO...these glow continuously without assistance for 12 years.
