Review: Bulbs fit perfectly in our RV’s Hallogen interior lghts - Just replaced the 51 Hallogen light bulbs in our 2004 Monaco Dynasty Diamond IV and couldn’t be happier. I can actually see at night! The light out put is awesome. We went with the bright white lights in the living space and then changed out the bedroom lights with warm white bulbs from a different manufacturer. I like the HERO-LED light bulbs much better than the other brand. Why? The bulbs were much easier to install as they are super slim discs with some compositors on the back side. They fit perfectly in our ceiling mounted hallogen puck style lights with round glass lenses. The other brand of warm white bulbs have a large plastic dome on the back/top side and are really too thick to install and keep the glass lenses in place. There is only one disappointment so far from installing these new LED bulbs. It sounds odd, but we are camping this weekend farther from local TV broadcasting towers and we are in the fringe coverage areas. Signalsckme and go on some chanels. OK, so here’s the weird thing.....if we turn off the LED bulbs, we get TV signal. Within 3 secs of turning them back on we lose signal. This has occurred over the past 4 days and always happens. I share this because these LED bulbs obviously give off some type of interference that impacts Digital over the air TV signals. Kind of scary.
Review: Beware it is on the bigger side - They are slightly big and may not fit may of the existing under cabinet lights. I had to come up with a creative way to make it work for me. Luckily it was easy and not a hazard. But the light is very good and bright and daylight. So you will see the right colors and contrast.

### ⭐⭐⭐⭐⭐ Bulbs fit perfectly in our RV’s Hallogen interior lghts

### ⭐⭐⭐ Beware it is on the bigger side
*by R***I on July 18, 2017*

They are slightly big and may not fit may of the existing under cabinet lights. I had to come up with a creative way to make it work for me. Luckily it was easy and not a hazard. But the light is very good and bright and daylight. So you will see the right colors and contrast.

### ⭐⭐⭐⭐ 2 out of 5 is good for baseball - not so good for lights - Replacement order works great!
*by F***M on August 18, 2015*

Bought these to replace motorhome halogen lights. Great price, but of the five lights only two worked. I paid $15 for one light at Camping World so I hoped these would be similar.... Not so much.... Complained to Amazon and they promptly shipped another set - these arrived and all 5 worked. I verified the three were still not working but am very happy to return them and have five working lights!
