Product Description
CAN Bus LED replacement bulbs can fit vehicle tail lights, brake lights, reverse lights, turn signals, and side marker lights. This 1157 dual-contact, dual-function bulb has 30 LEDs that create a 360° viewing angle for better, allover light emission with reduced hot spots. Error-free LED bulbs are designed to communicate with your vehicle's CAN Bus computer system and prevent error messages. Tower-style design with a BAY15D 15-mm bayonet base for easy plug-and-play installation—just twist to lock in place. The energy-efficient bulb operates within a 12-24 VDC range and is designed to last 25 times longer on your car, truck, SUV, or van than incandescent bulbs. Available in cool white, amber, and red. Not sold in pairs. Price per bulb.

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. |
Part NO | CCT / Wavelength CCT / Wavelength ![]() | Brightness Brightness For best results, the LED color should be the same as the lens color. If the bulb is behind a clear lens, use the appropriate color for turn and brake light functions. When installed in a housing that has a matching colored lens, red and amber bulbs will appear brighter than white LED bulbs - even though they have lower lumen outputs. As an example: a red lens will filter out all but the red portion of light from a bulb, so if the light being emitted from the bulb is all red, none or very little light will be blocked by the lens. The light from a white LED bulb contains very little light in the red portion of the visible spectrum, so most of the light that contributes to its higher lumen value would be filtered out by a red lens. This makes the white bulb appear dimmer than the red bulb. ![]() | Beam Angle Beam Angle Beam angle is used to express the width of the light emitting from the source. The narrower the beam angle the more focused the light energy is. Comparing two 40 watt lights one with a beam angle of 30(a) and another with a beam angle of 90(b), They both produce the same amount of light output but (a) will appear brighter in the beam angle compared to (b) at the sacrifice of light spread. ![]() | Current Draw @ Operating Voltage Current Draw @ Operating Voltage Current Draw is used to size fuses and wire for a circuit. Current draw is the amount of energy consumed by an LED or LEDs in an electrical circuit at a specific voltage, measured in amps (A) or milliamps (mA). | Price Ea. | Weight | Operating Temperature | |
---|---|---|---|---|---|---|---|---|
1157-CW30-CBT | 450 nm | 74/295 lm | - | 50/275 mA | $9.95 | - | - | |
1157-A30-CBT | 595 nm | 13/46 lm | - | 40/150 mA | $9.95 | - | - | |
1157-R30-CBT | 630 nm | 15/55 lm | - | 40/140 mA | $9.95 | - | - |
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. | ![]() |

Who knows?
I got these because they said “CAN Bus”. Received them quick from the vendor. Put them on one side and still got error message on my dash screen. I was super confused. I looked at the bulb and no where does it say the model type, so I could have been sent the wrong bulbs and wouldn’t know it. Which I think happened because the tiny boxes they came in looked partly mishandled, as if someone switched them hastily. Anyway, called vendor and they said they sent the right ones and that “CAN Bus” are not error free on 100% of the cars. I had to order resistors from them in order to work, which was what I was trying to avoid in the first place to avoid messing with cutting wires, etc., hence the “CAN Bus”. Installed them with the resistors and they work fine.

Good improvement
Replaced the incandescent brake/tail light bulb on my Triumph Thunderbird LT with this bulb. Brightness of the LED seems about the same as the incandescent but the LED brake light turns on faster which is the main reason I wanted to upgrade. I needed a CAN bus compatible bulb which this one is.

2014 Fiat 500e
These bulbs are not error-free in this application (2014 Fiat 500e). The bulbs do fit well, however, and are plenty bright for the intended use.

CAN Bus bulbs should work with most cars that have computers that notify you if a light bulb is burned out. However, some vehicles still might have issues - due to the unique electrical systems in these types of vehicles.

Vehical match pull down.
Product is good, service good, order comes quickly, but twice the vehicle match pull down has matched bulbs for my Harley Davidson which would not fit. Incandescent bulbs glass tapers out, LED's are barrel shaped which doesn't allow for bulb to be inserted far enough in to turn. Buyers beware ! PS they do have LED's with stock covers which work, but no amber color.

Error Message
These do not work on my 2013 Fiat. I get a bulb failure indication with no brake light illumination.
