HSUN 1157 BAY15D P21/5W LED Light Bulbs,16LED SMD3030 Chipsets 3200LM Extremely Bright Bulbs with Canbus for Car LED Turn Light Brake Light Tail Light Back Up Light and More,2 Pack,6000K White

I fitted these in red on a caravan as stop/tail bulbs and had no canbus issues from either car, they were very bright.Out of curiosity I measured the current draw which was 0.53 amps or 6.4 watts from a bench power supply set at 12v. In a car with engine running this would be nearly 14v which equates to 8.5w so these are probably the best and brightest LEDs around at the moment. A great buy. Remember to get them in the colour matching your lense. A white LED through a red lense will have losses compared to a red LED through a red lense.

I bought these on a bit of a punt. My car has very bad reversing lights (standard filament bulb type). Reversong down an unlit road every night, isn't much fun when you can't see where you're going, so I constantly had to keep my foot on the brake just for an extra bit of light. While these haven't entirely resolved my problem due to the design of the reflector in the lamp unit, they have significatnly improved it. Looking directly into them is like looking directly into the sun! On a better designed lamp unit I have no doubt they would be brilliant

I had enough every month to change the halogen bulbs so I decided to switch to LED after a few research I buy this one and I choose them for the lifespan 50k hours and for error-free. I have a BMW F30 and is no error in a dashboard so I`m happy with my purchase I will see about the lifespan. definitely, I would recommend this for all that want to change their standard halogen, reason #1 lifespan(from the description) 50k hours. and yes they are super brightupdate: yes they flickering so if you don't bother you can leave like that otherwise you have to code them.

Very easy to install, straight swap over. however I'm a bit disappointed with the performance of these bulbs,they are not as bright as I thought they would be.I decided to upgrade my bulbs after tinting my rear lenses as I was finding it quite difficult to see in the dark whilst reversing.Overall these led bulbs have improved the rear lighting whilst reversing, but could be much brighter.

Swopped normal P21W Filament Bulbs for these LED's in the reversing lights on my motorhome and what a difference!!!The increased brightness has to be seen to be believed. As for their longevity I can't answer, as I don't have to use reverse gear that often, but even if they don't last as long as the old filament bulbs I wouldn't go back to them.

The bulbs have very good quality and brightness, but they are absolutely not compatible with canbus. If you try to retrofit those you will end up with an alert light on the dashboard in the best case and with a super fast blinking light on your car.

Good LED very bright when on brakes and a good level for tail light when not.No bulb outage error message on my 2018 Ford Focus, however tried on my 2015 Transit Custom and reports bulb out.

Beautiful tail and brake LED Bulb which I am totally happy about.The build quality was great and every part of the bulb was nice.As you can see, the pictures show braking and tail light which is bright and a lovely red colour.
