Caterpillar DPL40 Glow Plug Relay

Hello Folks

I have a 1996 Caterpillar DPL40 forklift and the glow plug light stays on after startup, I will test the circuit later on and the relay, but the question I have can I substitute it for a generic relay that would be the same capacity (amp and voltage) instead of buying the gem style relay, the battery voltage is 24V system and it's a 6 cylinder Mitsubishi 6 cylinder engine diesel.
