LED Signal Kit too dark?

so I just got my amber LED signal kits from Jlevi and did a quick preview of what it would look like during the day. I have clear signal lens, and i swapped the tail light bulb with an amber LED and turned the hazard lights on. i was dissapointed in how dim the LEDs are compared to the clear yellow factory bulbs in the other tail light, and because they are so dim during the day, you only see the center "yolk" of the lens glow amber, the rest of the lens stays clear and unlit.

is this normal? does it need anything else to make it brighter? i haven't installed the side signals or the front ones with the resistors yet, but i can only imagine the same results. could it be that it's 26F outside right now?

i've tried Solaris white bulbs too and even though they are very white, they too are too dim during the day - so i am waiting for a new set of Solaris amber ones to come to see if those will look better... otherwise i have to stay with my bright clear yellow factory bulbs which isn't that pretty but very bright at least.

In the taillights, an led faces completely straight out, thus reflecting very little light in the tailight housing. The light that you see comes directly from the led, and is not reflected throughtout the taillight housing. There is no way to "fix" this, the two are not designed to work together. This problem doesnt really happen in the fronts because the led can reflect properly, but mine are still a little dimmer than stock.

The tailight turn signals are not as bright as the front turn signals because of the nature of the housing. You will notice that it is a VERY bright focused beam so while it does not illuminate the entire housing like a halogen bulb it will brighter but less of a light "filler/disperser".
