Do solar LED signs need an electrical connection?

No. The panel on the sign charges the battery during the day and the LEDs switch on automatically after dark. Because no cabling, transformer or meter is needed, the signs can be installed where there is no mains supply.

Do they work in cloudy weather?

The panel still charges under cloud, and battery capacity is sized to keep the sign running through days with little sun. Mounting the panel clear of shade and keeping its surface free of dust directly affects performance.

When are yellow-background signs used?

Yellow backgrounds mark temporary arrangements and construction-related risks: site and factory exits, roadworks and temporary speed limits. The colour separates them from permanent road signs, telling drivers the situation is out of the ordinary.

Can sign faces be produced to order?

The catalog carries standard faces — speed limits, stop, no entry, pedestrian and school crossings, bends, speed bumps, lane transitions. If you need a facility-specific face or size, send the request to our sales team.

Solar LED Signs

Solar LED traffic signs charge from a solar panel during the day and light their own LEDs at night. Faces include speed limits, stop, no entry, pedestrian and school crossings, dangerous bends, lane transitions and construction or factory exits, with yellow-background variants, all listed for wholesale supply.

Built for Locations Without a Power Supply

The core advantage is independence from infrastructure: no cabling, transformer or meter is required, so signs go up quickly at construction sites, mine sites, rural junctions and the gates of agricultural and energy facilities. The panel charges the battery through the day and the LEDs come on after dark.

Active light draws a driver's attention from further away than a passive reflective sign, particularly in fog, rain and dust. For fixed vertical traffic signs and reflective material classes, TS EN 12899-1 is the reference standard.

Speed limit faces: 20, 30, 50, 70 and 90 km/h in white and yellow background
Mandatory and prohibitory faces: stop, no entry, no overtaking, compulsory direction
Warning faces: dangerous and continuous bends, speed bump, loose surface, works ahead
Pedestrian priority: pedestrian crossing, school crossing, blue crossing signs
Work-zone layouts: lane transition, lane narrowing and truck-mounted arrow boards

Construction Site and Industrial Use

Yellow-background variants exist for temporary, attention-critical warnings: site exit, factory exit, vehicles may emerge, traffic control and yellow-background speed limits. The background colour tells drivers this is a temporary arrangement rather than a permanent road sign.

Where a warning is needed but no sign face applies, solar flashers are used instead. For work-zone plans that combine signs, flashers, cones and barriers, our sales team can help with product selection.
