This upgraded version offers the same technical specifications as the old Model 4000 but there are a couple of key improvements that make this Evolution 4000 model the superior option.
See below image for reference. New H4 bulb on the left, old on the right.
- Smaller bulb sizing means less fitment issues
- Side exit cabling (on most base types) means little to no dust cap fitment issues
- Smaller, less intrusive power module which is now hard wired in with no connector plugs
- Shorter overall length to help fit most headlights
Some vehicle electronic systems may conflict with the LED bulb. There are a limited number of vehicles who’s electronic systems may require the addition of a CANbus unit during installation. The CANbus unit will allow the vehicle’s electronics to accept the LED bulb into its system.
Before fitting the LED headlight conversion kit, we suggest you consult a qualified Auto Electrician or call Invision Sales to see if your vehicle is listed as requiring a CANbus product. The majority of vehicles will not require any additional products.
