All specifications are subject to change without notice. 1. CAN Bus LED bulbs are simple plug-and- play LED bulbs which are made specifically for CAN Bus-equipped vehicles. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly. To see if your vehicle operates with a CAN Bus system, simply remove the bulb you're looking to replace, start your vehicle, and if you have a "Bulb Out" message on your dash you have a CAN Bus system. |

| Lumen meters are a great way to measure white light output but can be deceptive for colored bulb intensity. Lumens measure light wavelengths in all colors of the visible spectrum. Because multiple wavelengths create white light and colored bulbs are a single-wavelength source, colored bulbs will have lower lumen readings. However, they will appear equally as bright as a white bulb. |  |

brighter backup lites on less power
on my 2001 Chevy Lumina "smoothtop"
switched out my 3156 incandecent bulbs to these in cool white -- VERY happy w the results!
my backups [ reverse lites ] can also be activated w a console mounted switch as they include several LED strobes and LED lite panels mounted on the trailer hitch and under the rear sides for scene illumination and warning -- I'd noticed a reluctance of some of the strobes to flash w proper intensity & speed and figured [ even tho the fuse didn't blow ] that the backup circut was overloaded a leetil -- so, I ordered these, changed em out, and *now* the strobes flash proper like and the actual *backup* lites are much brighter

Replace the back up bulb on my F-350 Super Duty
Replaced the 3156 back up bulbs on my 2001 F-350 Super Duty. The old bulbs drew 2 amps each. These new bulbs draw only .5 amps and are 4 times as bright. I mean seriously BRIGHT. Just barely fit, the new bulbs are longer.
Great service and got the bulbs in two days to Colorado.

Problem Installing
The Electrical connection pins on the base of the bulb were superimposed.(Opposite of the existing 3156 bulb) I had to carefully straighten them and bend them the opposite way to make contact with the socket terminals.Also the black plastic base of the bulb was to big to fit through the hole in the fixture bezel. I filed the hole to fit the bulb.(Minimal amount) The bulb was quite bright and works great other than the two glitches I noted!

Super Great
I bought 2 of the cool white and as a replacement for my 04 Mustang's reverse lights and they worked great, super bright and very attractive when you're looking at them, but don't throw out as much light do to the design of the bulb and my light housing. The way a regular incandescent light bulb is shaped it can throw more light to the back of the housing and in turn out on to the road, but since these bulbs have a flat bottom they don't, maybe something to improve on later but never the less still very pleased and would recommend. Will be buying more bulbs from SBL soon.
