JW Speaker understand that their traditional LED Bulb Kit, the Evolution 4000, may not physically fit all vehicles. There have been some instances of the aluminium base hitting the plastic moulding of the headlight, stopping the bulb from locking and securing into place. For this reason JW Speaker have designed a range of LED bulbs called Direct Fit. These bulbs share an identical connection system to the halogen bulbs they are going to replace, meaning there is no extra wiring or modules to fit into the headlight. This range really is as simple as removing the old halogen bulb and replacing it with the new LED bulb. In the most recent update to the range, some of the products that have a right angled base have had a slight sizing modification to allow for better fitment into vehicles like the Ford Ranger where the plastic moulding of the headlight stopped the bulb rotating into place properly. Vehicle electronic systems can still conflict with the LED bulb. This range of bulbs comes with some built in CANbus technology to cancel out those issues however there are some vehicles with electronic systems so technical that they require an additional CANbus unit during installation. The CANbus unit will allow the vehicle’s electronics to accept the LED bulb into its system.
