Full Retrofit Package We sell the full retrofit sign package as a lump sum per DMS upgraded, so there are no surprises with the cost or the services provided.

DMS Technology Our retrofit kit uses the same technology as a new DMS, but it fits within your existing sign housing for cost-efficiency and ease of installation and transition.

Unique Retrofit Method Retrofit includes sign survey(s), aluminum supports for new components, full factory wiring, standard factory acceptance tests, a 48-hour burn-in test, retrofit installation assistance, site testing and commissioning, and the same warranty as a new DMS .

Easy and Fast Retrofit Our methodical retrofit approach means we can retrofit a typical DMS in just 2-3 days, and we’ll keep you updated on retrofit progress the whole time.

Any Type of DMS We can retrofit any DMS technology: from fiberoptic, to hybrid, to flip disk, to LED. We have successfully used a retrofit package on 7 different sign brands and more than 20 DMS types throughout the US. See our References page for a list!
