| 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!
