Auto Air Conditioner Leak Detector Tool Flashlight Oil AC UV Dye Leak Test Detection Kit Pro 68 LED Flashlight with UV Protective Glasses

Works great for finding radiator leaks. I bought some dye from Harbor Freight and this saved me from having to spend money at the mechanic shop. The glasses didn't help at all though, I saw the dye better without them.

Works really well. Arrived as expected. Do yourself a favour and eliminate as much light as you can for the best result of tracing the leaks. PRO TIP for DIY'ers: DO NOT wash the engine bay to then use the Dye. You'll wash away any traces of the leaking Gas/ Compressor Oil.

*Update* Seller contacted me through Amazon and quickly sent a replacement light. Replacement light works great with no issues. These UV flashlights really do put out plenty of light and certainly enough to track down an AC leak (using UV Dye, of course). Good inexpensive DIY alternative... Just an FYI - Take the batteries out of the unit when storing as AA have a tendency to leak. Good hunting! This unit puts out a good amount UV light, particularly if you use it in dim to dark light, but right after the first use, it stopped working. I replaced the batteries. No good. Took the thing apart and cleaned all contacts. No good. Made sure all batteries (3x AA) were correctly oriented and the battery cassette was in the correct way. Nope, unit was dead. Too late to return so I threw it in the trash.

Bright light identification made easy
