Hello there, and welcome to my guide for LED upgrades for the interior and exterior of your Chevrolet Bolt EV model years '17~'21. Some of these interior upgrades can also be applied to the '22 and later using incandescent bulbs. While I have shopped for and tested various LEDs thoroughly to find what works best, keep in mind that replacing the lights on your Bolt EV is not recommended by the manufacturer and poses risk for electrical interference or other issues. I do not take responsibility for any problems caused as a result of this guide. Perform only at your own risk. That being said, I've been using the following light upgrades for well over a year, and they work great without issues. I aimed for upgrading the interior light to 6000k color tone LEDs that support the courtesy dimming, 6000k LED license plate lights, 6000k LED backup lights, and LED blinkers that aren't too bright and don't trigger system errors. I ignored the rear red lights that only turn on if the trunk is open. The HID headlights are also already plenty bright and efficient. Take a look (note that the night shots make the lights appear a bit brighter than in-person): If this kind of upgrade appeals to you, links for the LEDs and important notes will be found below. But before that, here's the correct way to replace the cabin/map lights without breaking some of the clips that hold the overhead unit into place. Trust me, do it this way. Learn from my mistake of breaking two of them trying to follow guides posted by others here. Don't try to get to the cabin lights in the overhead unit like this! It will break some of the plastic clips, and it wont seat back quite right. Once you've popped the clip free, pull the lens downwards with a gentle force to pop the clip from the other side of the lens. Now you're in! Small fingers or even a thin screwdriver or pry tool are needed at this point to remove the old bulbs so you can insert the new LEDs. Make sure the light power is OFF to prevent any electrical accidents! Here's the lights I used: Interior cabin lights: https://www.amazon.com/JSVSAL-Non-Polarity-Generation-Interior-Courtesy/dp/B07TZ5Q7B8 These lights support the courtesy dimming feature, and are plenty bright without washing out colors. You can actually see inside your car at night! The ones linked say 4500k, but trust me, they're definitely 6000k in reality. Note these are polarized. License plate bulbs: https://www.amazon.com/dp/B01BDWLZHU This one was tricky, since some bulbs don't cast their light quite right, or kept burning out. These Sylvanias, however, have been perfect. Note these are polarized. Backup lights: https://www.amazon.com/dp/B07ZLQ229N These are the perfect upgrade for your backup light in brightness and color tone. The lights are not polarized, but they do angle their light differently depending on orientation (one way points a little more downwards than the other). I set both of mine in the more downward position. Blinker lights Amazon.com: SIR IUS LED RLS 7440 7440A Built in Resistor Anti Hyper flashing LED Bulb Turn Signal Light Amber Orange Color Full Aluminum Body Single Filament Error Free Pack of 2 : Automotive These have a built-in resistor to prevent that pesky "check light bulb" error message as well as hyperflash, and are plenty bright. There is the potential for these to hyperflash if left running too long, but I've never had it happen yet in so-cal summer heat. Can you show how you replaced the license plate LEDs? I can’t find any guides on this forum There is a recess on one side of each of the plastic covers for the license plate lights. Gently wiggle a flat head screwdriver under the lens and pop the covers downwards to open them. When putting them back, put them in in the reverse they came out. Also make sure they're snapped in SECURELY. They might make a click like they're secure, but make absolutely sure. I had one pop back open after being careless and thinking it was closed flush.
