I have a 98 XJ to which I just installed a set of Hella H4 sealed beam type headlights. The bulbs are replaceable. I bought them because they don't need a wiring upgrade. Hella's aare 55/60w. I thought they would be brighter but don't seem to be.
Is there something that I am missing - do they need to be readjusted, wiring upgraded, etc.
I have a set of Hella offroads with 55/60's and they seem twice as bright.
Any help would be great.
