With LED bulbs --> similar is Never the same! Yes I did add the wire to the bottom slot and that made a slight improvement. H4 COB Leds and leds with large emitters do not focus well and they have a soft cut off. Rectangular COBs are better than round ones. The Phillips style with 3 or 4 inline emitters create the sharpest cut off line with a thin beam pattern which IMO is best for long range vision (DEDC). The wider emitters give a taller beam and better lights up the close in stuff which is better for off road and windy roads. but you do not want too much close in lighting because it limits your ability to see far. So you have to match your main led to your riding style. Then you can add aux lights for other conditions. Which LED do you have that is similar? I bought another "similar" COB led with a shield that was horrible. There is still a lot of junk out there. We need to help each other by letting others know what works well on your bike.
