If the sign is too bright when internally illuminated and uses fluorescent lamps, use black electrical tape to wrap each lamp in a loose barber-pole fashion. Remember that this is only to reduce the lamp output, and too much tape will overly darken the sign. Do not use this method with internal LED lighting.
For instructions on reducing the brightness of your LED display, see the Software page.

The internal illumination for the sign cabinet is driven by a ballast for fluorescent lamps or power supply for LED lamps.
Cleaning the Sign Cabinet
Upon the arrival of your new sign, we recommend you wax all painted surfaces of your sign (the cabinet, legs and any trim) with a clear automotive wax. Occasional re-application of a wax polish maintains the look of your sign while slowing down the aging and weathering process. Approved products to wax your sign are Johnson Paste Wax, Turtle Wax, or Meguiar's Glaze. To remove calcium or lime deposits, use a solution of 10 parts water to 1 part vinegar or a solution of 1 part water to 1 part baking soda.
Cleaning the Sign Face
The sign face is the translucent plastic portions of your sign, including the header area, logo area and vandal cover. Clean periodically with the following steps to prolong the life of these components:
For best results, treat graffiti within the first 24 hours and use the appropriate solvent. For spray paint and other paints, mineral spirits should be used first. If necessary, stronger solvents like acetone, lacquer thinner or a paint reducer may be used. For dried egg and permanent marker on metal surfaces, 3M Bug & Tar, WD-40 or isopropyl alcohol can be used.
If possible, test your solvent in a non-conspicuous area before continuing. Start at the top of the graffiti and move downward with gentle rubbing motions using a soft, lint-free cloth. Do not use excess pressure, as this may negatively affect the sign coating. Continually move over the affected area and change the cloth frequently. Repeat until the graffiti is removed.
Cowling is the metal sheet spanning the sign's legs, giving the support structure a solid pedestal appearance. Cowling can be added or replaced using the following method. This procedure should only be followed when ambient temperature is above 60°F.
Trim is the metal accent piece added to the top and bottom of a sign cabinet. Because the bottom trim is typically welded to the support structure, these instructions apply to the top trim piece only.
Vinyl letters and numbers can be added to the painted surfaces of your sign. How they are applied depends on whether the letters are for dry or wet application. If you are just replacing one or two letters, there should be no need to wet the vinyl; it can be applied dry. Before beginning, clean the area using the cleaning the sign cabinet instructions.
