The 240 BLITZ and 240 XGT offers a performance level suited for those who require extreme long distance visibility such as professional remote long haul truck drivers. When focussed to its tightest spot there are few lights in the world that can compete when distance does matter. Durable polycarbonate filters should remain fitted to driving lights at all times. Capable of absorbing road grime and bombardment for many a highway mile, these replaceable filters should be renewed from time to time to protect your investment and maintain maximum beam output. Driving light filters feature the distinctive Lightforce script logo. FEATURES Crystal Blue filters are used to increase clarity when driving.
