Review on Waterproof Marine Fuel Level Gauge 52MM for Boat | 7 Color Backlight | Adjustable Signal | Car Truck Motorcycle | 12V/24V | Fuel Gauge for Gas Tank Lever | 0-190ohm 240-33ohm 240-30ohm 0-180ohm 10-180ohm by Seuz Lundien

Based on our own experience, this backlight was a complete waste of money. The pros were that the product was advertised as waterproof and adjustable. However, its waterproofing abilities were extremely unreliable, and the adjustable feature was far from user-friendly. We found ourselves constantly struggling to get it to properly function. The cons of this product far outweigh any benefit it promises. It's simply not worth the investment for any serious automotive owner.
