These bulbs are completely plug-n-play meaning you just pull out the old bulb and plug this one in! no cutting, crimping, or soldering necessary.
As seen in the picture, the stock, and replacement halogen bulbs, are very dull and can hardly be considered a light!
These LED's are much brighter and make the side markers stand out much better, especially if you have them tinted! Great upgrade for a stock look... but much brighter!
