NEW! Blade Fuse Upgrade Kit for the Mercedes-Benz W124

December 1, 2024 - Holy Grail Labs, a premier supplier of engineered upgrades to classic automobiles announced pre-orders for the W124 Blade Fuse Upgrade Kit, an easy-to-install kit that upgrades the unreliable, melty, torpedo fuses found in all Mercedes-Benz W124 models to modern, reliable blade-fuses.

The kit addresses one of the biggest causes of electrical problems in classic Mercedes-Benz cars—the ancient and unreliable torpedo fuses. The HGL kit, which is based on the proven engineering of the kits HGL has been providing to the BMW community for years, includes LEDs that show green for any circuit with power and red if a fuse is missing or blown making it easy to identify blown fuses. The LEDs can be disabled via a switch.

"W124s and electrical issues go hand in hand unfortunately", said Vincent Raciborski, a beta tester, "Despite practically being built as a road-going tank, they can be complete nightmares when things go wrong in the electrical department. This little product eliminates a huge issue."

The kit fits under the existing fuse box cover and includes sockets for four spare fuses. Included are a full set of blade-style fuses.

Installation requires no special tools and can be completed in about an hour. 

The Mercedes-Benz W124 covers the E-class series made between 1984 to 1997 (e.g. the 200E, E320, 500E, and the E36 AMG Coupe). The new Holy Grail Labs W124 Blade Fuse Upgrade Kit is compatible with all W124 cars.
