Federal Signal 454100HL 25 Highlighter Suction Cup Review

Based on my experience using this automotive suction cup light, I cannot recommend it to anyone. While it does provide some illumination, it's not nearly as bright or effective as other similar products I've used .The suction cup is also weak and falls off easily making it frustrating to use when driving..

According to my experience this suction cup warning light is incredibly bright and easy to install in a pinch... It`s great for emergency situations or simply providing extra visibility on the road. The highlighter color really pops and grabs attention. The only downside is that it does require a power source, so it may not be as portable as some other emergency lights..

super bright, great deal at $145. Super bright, it needs a magnetic keychain to change the belt pattern. Sigfed sells a switch called sw2, but it's not available from Revain.
