Review on HOTSYSTEM LED Light Bulbs 1156 1141 7506 P21W BA15S 18-5050SMD For Car RV SUV Camper Trailer Trunk Interior Reversing Backup Tail Turn Signal Corner Parking Side Marker Lights(WarmWhite,Pack Of 10) by Chris Morales

They start off great almost like a REAL LED bulb, but not as bright as they say they are, and not as bright as 18leds per unit SHOULD and normally DO produce. NO biggie right.WRONG they start off 60%-70% brightness of EVERY brand ive bought from auto parts stores (yes there cheaper but you can get bulbs out of the trash that are broken for FREE) i say this because after running for a couple days (my RV's lights inside are DC 12volt) they start DYING one by one they lose there LED's from 18 to 12 to 6 , then they ALL flicker as they settle at between 0 and 9 leds which are each HALF brightness unless you flick them then you see the 9 of 18 get brighter.Theres junk soldier (probably zinc mainly or a non alternative) connecting the panels and they all fail at the joints.
