RADIANT Technology has introduced the Bingo 6, a small horizontal fuel float that can be used at any point in a fuel tank to detect the presence — or absence — of fuel.
The fuel float can be paired with any alarm light or indicator, such as the company’s 100db aural annunciator, company officials said.

Specifications:
- Usable for either up or down orientation
- 32 volts maximum
- 100 milliamperes maximum
- Includes black 15-inch wires
- Polypropylene material for compatibility with gasoline and water (alcohol is prohibited)
- ½ inch NPT for installation in any tank
- Overall length of 3.2 inches
- Use with any light or company’s 100db aural annunciator
Priced at $49.95, the fuel floats are expected to start shipping in late April 2025. The company’s 100db aural annunciator is available for $29.95.

Absolutely brilliant (radiant? LOL ) idea BUT.. I don’t recall any “spare” holes in my old airplanes tanks. Inexpensive smart and probably doable as a NORSE installation (minor alt. A&P w logbook/maint record entry) but having to pull tanks and weld a bung is low on my list of things to do this week…. on any of my, or my customers airplanes. At build or restoration, EXCELLENT plan. I can see this as a smart inclusion in newly built aircraft immediately.
