As a responsible seller we have to advise you that these items or any other LED lighting systems are not always compatible with most modern cars / vans / pickups with factory fitted tow bar electrics. (modern as a guide is considered from 2005 onwards)
The remainder of modern cars / vans / pickups with non- factory fitted tow bar electrics are still not compatible as they will not meet the legal requirements for an audible / visual warning of the operation / in-operation of the indicator.
We strongly recommend that before purchasing these items that you check with your dealer/manufacturer to establish if your vehicle whatever it’s age is compatible with LED lighting systems.
Unfortunately there is no list available advising which vehicles are and are not compatible.
