Note:About decoding Not suitable for all truck vans, such as Volvo, Mercedes, Scania and Land Rover vans. If Volvo, Mercedes-Benz and Land Rover trucks buy this type of truck light, the buyer needs to go to a car modification shop to refresh the driving computer or install a 24v truck special decoder (it may not be able to decode after adding a decoder), it is best to go to the car shop to refresh the driving computer. That way nothing goes wrong. Product Description: Led Chips: Super bright CSP Chips.
