makes LED tail light bulb replacements that have additional LEDs aimed to the side so that the car reflector distributes the light around like an incandescent bulb, and are better than the directional LED bulbs. However the review I read of them indicated they were still a pretty intense hot spot, only moderately better than other LED brake light bulbs, but not as difuse as a regular bulb. They are also about $40 per bulb!
