I have worked with James multiple times this year on bulbs for my ’89, Dodge, W350 single wheel/cab Cummins and my ’93, Dodge W250, club cab Cummins and couldn’t be happier with the headlights. The dim yellow factory headlights these trucks came with are anemic and dangerous. Converting to Hella headlight globes from Amazon (must trim the trucks headlight buckets so they fit) then installing Diesel LEDS, LumX Set (9300) H4 style bulbs is the way to go and well worth the investment for my older eyes. I started with their impressive reverse bulbs (1156), and now have their rear brake/turn signal bulbs (red 1157), front turn signal bulbs (amber 1157), and front side marker bulbs (194) on order. All the LED bulbs I have purchased from Diesel LEDS are plug and play without flicker because everything you need is built into each bulb, simply install it. Old-fashioned service with modern lighting solutions… what’s not to like? Highly recommend Diesel LEDS and James Collins fabulous service.
