You might think that this bulb only has 42 watts, but, believe me when we tell you- this bulb is super bright!
These LED bulbs are used to replace factory 3157 bulbs that gets so hot it makes the inner part of your head light lens turn milky or foggy.
So if you just bought a new head light or are planning to get one, don't make the mistake of using this bulb .
If you are using these for FREIGHTLINER CASCADIAS, you will have to install resistors to keep it from hyper flashing. Or, check our Plug n Play Switchback 3157 for Cascadias. It has a built-in resistor to avoid hyper flashing.
