LED replacement bulbs

[J. Henley 17]

The reflective crap in my passenger taillight is pretty much gone, so it looks almost like I've got a taillight out. I plan on fixing this by blacking them out and using LED bulbs. From my understanding, the LED bulbs are more focused and don't really use the reflective crap, so I'd get circles lit up on my housing. Would it still be noticeably darker?

putting covers on your taillights takes away the "reflection" , so it basically dims the lights alot, and only gives out light..

hard to explain i guess but yeah

i think the LED' bulbs make the signals flash fast, like they do when you have a bulb out.
