Bomag 05755655 Indicator Relay

The Bomag 05755655 Indicator Relay is a genuine OEM electrical component designed for a wide range of Bomag BW tandem rollers, single drum rollers, and pneumatic tyred rollers. As a direct OEM replacement sourced from Bomag, this indicator relay meets the original electrical specifications required to keep your machine's signaling and warning systems operating correctly. Compatible with an extensive lineup of BW-series machines — including tandem rollers such as the BW 120 AD, BW 174 AD, and BW 203 AD-4, single drum rollers such as the BW 177 D-3, BW 213 D-3, and BW 225 D-3, and pneumatic tyred rollers including the BW 12 R and BW 24 R — this part covers one of the broadest fitment ranges in the BW product family. Selecting the correct part number 05755655 ensures you are installing an exact-match relay built to Bomag's original design.

Key Features

• OEM Electrical Specification — manufactured to the original switching and load ratings required for Bomag roller indicator circuits, so signal behavior matches the machine's designed operating parameters
• Drop-In Electrical Replacement — this relay uses the same connector footprint and terminal configuration as the original, allowing direct installation without rewiring or adapter harnesses
• Broad BW-Series Coverage — fits Bomag tandem rollers including the BW 100, BW 120, BW 135, BW 138, BW 141, BW 151, BW 154, BW 161, BW 164, BW 170, BW 174, BW 180, BW 184, BW 190, BW 202, BW 203, and BW 205 series, single drum rollers including the BW 142, BW 145, BW 172, BW 177, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, and BW 225 series, and pneumatic tyred rollers BW 12 R and BW 24 R, as well as C-series rollers
• Signaling System Integrity — a failed relay disrupts indicator and warning light circuits, leaving operators without critical visual cues; replacing it promptly restores full electrical signaling function
• Electrical Safety Compliance — indicator and warning systems are a machine safety requirement on job sites; installing a genuine OEM relay ensures the signaling circuit performs to Bomag's original design intent and meets operational safety expectations

The indicator relay is an electromechanical switch in the roller's electrical system that controls the pulsing of indicator and warning lights by opening and closing the circuit at a timed interval. It acts as the heartbeat of the machine's visual signaling system, ensuring lights flash at the correct rate to alert operators and bystanders. When the relay fails or degrades, indicator lights may stop flashing entirely, flash at an incorrect rate, or remain permanently on or off — any of which can compromise site safety and make fault diagnosis more difficult.
