The SAS Mobile ‘SID’ is Solagen’s portable, vehicle activated warning sign for multi speed zone use.

The mobile ‘SID’ uses a built-in radar to detect and display a wide range of real-time vehicle speeds and incorporates a selectable speed threshold to allow tailoring for changes in location. The slim, all-inclusive design of the SID unit allows customers the freedom to install and relocate their products at any time.

The SAS Mobile ‘SID’ package

Solagen’s Mobile ‘Speed Indication Device’ comes complete with the main sign unit, 4 rechargeable batteries, and simple fixings for mounting the sign to various sizes of sign post.

Starter Pack

A Starter Pack, which includes the tools required for fitting the unit and charging the batteries from the mains, is required when purchasing a ‘SID’ for the first time.

These kits also include a travel bag for the sign unit (and solar panel bag if relevant) and a manual, which includes installation instructions as well as guidance on battery use and setting the speed threshold. A Solar Starter Pack is recommended when purchasing the ‘Speed Indication Device’ with a Solar Adaption Kit.

Additional ‘SID’s can be purchased without the need for extra starter packs.



Additional items are available such as extra installation packages which can be left in situ on posts making relocation between several sites even more straight forward.

Additional battery chargers and spare batteries can also be purchased if required. These can help speed up the process of recharging batteries if the solar option is not used.

Solar Adaption Kit

A solar adaption kit may be ordered with any ‘Speed Indication Device’ sign package or added to an existing unit at a later date.

The addition of a solar panel kit to an ‘SID’ installation allows the batteries to be continuously charged by the sign – where sunlight is good this eliminates the need to visit site for battery recharging altogether and even where sunlight is poor the period between site visits can still be extended.

The solar panel provided can be quickly removed and installed on both 76 and 89mm posts, allowing for the rotation of the solar panel to various locations, if desired.


SAS ‘Speed Indication Device’ Options

The SAS Mobile ‘SID’ sign face is available in 300mm numerals with Slow Down. This size allows for a highly visible 7-segment speed display without compromising portability. The sign includes a ‘YOUR SPEED’ vinyl header for clarity and a 300mm ‘SLOW DOWN’ ensures a clear warning is given to drivers that exceed the speed limit.

Bespoke vinyl patterns and wording may be possible on request.
