Features Direct replacement for factory 28mm festoon bulb Adds more modern LED appearance Plug and play simple installation Overview Design. The 28mm SMF1 LED bulb is a direct replacement for any 28mm-size bulb commonly found in vanity mirror lights in many vehicles. Populated with one 5050-size SMD the SMF1 upgrades the factory yellowish incandescent bulb to a more modern LED appearance. The SMF1 was designed with an embedded load resistor and implanted diode for superior reliability. With its durable metal terminals it will fit snugly in the socket and its light weight means it won't vibrate loose over time. Reliability. Unlike other bulbs on the market this bulb is built with constant-current circuitry along with transient suppression. That means this bulb will last for years not months with no flickering or failure. And like every Diode Dynamics product it's backed by an industry-leading three-year replacement warranty.

We test the true output in-house and provide you the real numbers to compare. Colors.

Prom Time🙌🙌
Color: Gold, Size: Medium, Color: Gold, Size: Medium
I purchased this suit for my son’s prom, and it exceeded our expectations. The fit was true to size, the material feels good quality, and it looks very sharp in person. He was comfortable wearing it all day, and it gave him a polished, confident look for his special day. I would definitely recommend this suit to anyone looking for a stylish and well-fitting option!

Excellent quality for an excellent price tag
Color: Blue, Size: Medium
The suit arrived in 2 days after ordering; it arrived in excellent condition, was wrapped in clear plastic, however it was only in one package and should have been wrapped in a second layer in case of accidentally opening during the shipping process.
The suit was folded very neatly, I'll keep it as is as it's a gift for a friend of mine who is a musician and he will use it for
performance on stage. The size was M and correct. Unfortunately, it has arrived in the wrong color, I ordered blue, and purple has been delivered.
I hope, he likes it anyway. I'll keep it as it is too inconvenient for me to exchange it and ship it back to the sender.

Beautiful suit
Color: Purple, Size: Small
Suit is better than I expected. Bought this for my son for prom. The sequins POP. I am highly satisfied with this purchase. My son is 5'6 about 130 lbs and I ordered a size XS and it fit perfect. The only complaint I have is there is a hole for a button but no button is attached to the suit. Besides that, GET IT.

Great suit
Color: Purple, Size: X-Small
Fit my husband perfectly for our friends wedding and it was comfortable. It doesn't get wrinkled fast if at all. The quality was not bad for the price.
