Review on HIKARI VisionPlus H4/9003 LED Bulbs: 15000LM, Dual Beam, 30W TOP XHP50.2 LED - 100W Equivalent, HB2 High Lumens Kit, Cool White 6000K, IP68 Waterproof - Halogen Upgrade Replacement by Christopher Gulledge

When used in a Cibie E-Code 5 3/4" round headlight kit the chips are not in the exact same position as the standard H4 filament. When used on the road so it produces fantastically bright areas and very distinct dark spots. It's not a constant blanket of light across the entire field of view, and while it's slightly better than competitor incandescent bulbs I've tried before, they have a different problem where I find them An additional problem is that the chips are not in the exact same position as the standard H4 filament, it hits the reflector in a different orientation and creates huge side flare. This caught my eye when working on a semi passed trailers during a night test drive with them, the amount of light directed from the side illuminated the truck as if d The lights would be aimed straight at the truck, and not just at a low angle as intended. for the light He shrugged and walked to the full height of the trailer. In photo 1 the light and dark spots of the lamp are clearly visible, although it is still light so I waited for the dark to take the same picture and then it really becomes visible. Image three was on a flat road and they are visibly bright but can still see dark spots. The last issue is that the heatsink/fan assembly doesn't allow for a weather seal as it's too big. So if I rode it in bad weather, moisture could get into the bulbs and corrode the reflector. Most likely they will be sent back.
