Using just 16PCS 3030-SMD LED chips to produce peak output, the 3030-SMD LED generates less heat compared to other bulbs that sometimes use up to 60-SMD chips at the market. The 3030-SMD LEDs are mounted inside the lens, which sits atop a ribbed aluminum heat sink; an integrated thermal resistor reduces output as a secondary level of protection.

LED bulbs are very easy to install. You just have to plug it in the socket. (LED bulb has + AND -terminal. If it doesn't light up after inserting into the socket, all you need to do is insert it oppositely.) How it Works (check the gif animation):
