Red Zone Light (Forklift Pedestrian Warning)
A red zone light is a forklift-mounted LED projector that puts a red marker on the floor — either a spot ahead of the truck or lines down each side — so pedestrians can see the truck’s path before they see the truck. No standard makes it mandatory: ANSI/ITSDF B56.1 4.15.2 leaves the decision to the user.
Two different products share this name, so specify the pattern rather than the name. Jungheinrich projects a red dot roughly 3 m in front of the truck. STILL projects two strips of light to the left and right. Hyster uses zone lines on either side to mark the distance pedestrians should keep. Projection distance on the side-line types is set by mounting angle on site, which is why manufacturers do not publish a figure for it.
What the regulations actually require
OSHA does not mandate warning lights. Its 2012 letter of interpretation states that OSHA does not specify that powered industrial trucks must be equipped with flashing lights or back-up alarms. ANSI/ITSDF B56.1 4.15.1 makes only a sound-producing device mandatory; 4.15.2 then says the user shall determine whether operating conditions require additional visual devices such as lights or blinkers, and is responsible for providing and maintaining them.
The one lighting requirement in 29 CFR 1910.178 is (h)(2): where general lighting is less than 2 foot-candles — about 21.5 lux — auxiliary directional lighting shall be provided on the truck. That is a work-lighting rule, not a pedestrian-warning rule.
Absence of a specific rule is not absence of liability. OSHA notes that an employer whose workplace presents this hazard and has not taken feasible steps to mitigate it may be cited under the General Duty Clause, 29 U.S.C. 654(a)(1).
Retrofit approval in North America
Adding a warning light to an existing truck counts as a modification. Under 1910.178(a)(4) it requires prior written approval from the truck manufacturer; where the manufacturer will not give it, OSHA’s 2004 interpretation accepts written approval from a registered professional engineer instead. Fleet buyers who skip this step often discover it during an audit rather than at purchase.
Specifying one
Decide the pattern (spot ahead, lines to the side, or both), the mounting height and angle, and the colour — no standard fixes the colour, and red is common where blue is already used for other markings. Sealing matters more than output in cold stores and wash-down areas. See our forklift safety lights for both spot and zone-line types.

A blue spot light projects a pool of blue light onto the floor several metres ahead of or behind a forklift, giving pedestrians a moving cue before the truck itself comes into view. STILL specifies approximately 5 m in front of and behind the truck; no standard requires the colour to be blue.
IP Ratings (IP65, IP67, IP68, IP69K)An IP (Ingress Protection) rating is a two-digit code defined by IEC 60529 that specifies how well an enclosure resists dust (first digit) and water (second digit). IP69K is the highest rating, covering high-pressure, high-temperature wash-down.
