Typically, a T4 will have around 10V to each headlight, which has more effect on the effectiveness of your Transporters lights than you might think. Fear not, the answer lies within an easy to fit replacement headlight loom.
The headlight loom from Dubz by Dan claims to restore your T4 lights to actual battery voltage of around 12.4V.
Fitting is really easy with our installation taking just five minutes. With just five connections, including easy fit male H4 trigger connectors, the headlamp loom covers both full and dipped beam circuits to both headlights. The loom is plug and play and 100% reversible and is available to fit all short-nose T4s.
