The second end of the elongated member is received within a fluid reservoir housing. The elongated member is composed of a heat resistant material to prevent degradation from exposure to high temperatures. The second end of the elongated member measures fluid levels within the fluid reservoir. The handle comprises a housing, a switch disposed on an exterior of the housing opposite the elongated member, a power source enclosed within a waterproof interior volume of the housing and a light source disposed on an exterior of the housing opposite the switch. The switch, the power source and the light source are operably connected to each other. The switch is configured to selectively actuate the light source.
