For 2005 through 2010 models, the Chevy Cobalt headlight bulb size is 9007 (also known as HB5) for both high and low beams.
Can I change my Chevy Cobalt headlight bulbs with LED headlight bulbs?
You can, but you need to make sure that the LED bulb matches the interface and voltage of the Chevrolet Cobalt halogen headlights. And the LED bulbs need a good heat dissipation system to ensure that the LEDs can work properly. Most importantly, you need to make sure that the replacement complies with local traffic regulations to avoid affecting the angle of illumination of the lights. If you are not sure, it is better to consult professionals or go to a headlight tuning store for installation.
How to change a Chevy Cobalt headlight?
2005-2010 Chevy Cobalt headlight bulb replacement is not difficult and can be easily done by following the steps below.
1. Open the hood.
2. Remove the headlight assembly. Unscrew the two bolts at the top of the headlight. Gently pull the assembly forward.
3. Disconnect the wiring harness.
4. Twist and remove the bulb socket.
5. Replace the old bulb with a new bulb (avoid contact with glass).
6. Reinstall all parts in reverse order.
Finish!
What are the benefits of replacing halogen bulbs with LED bulbs?
The benefits of replacing halogen bulbs with LED bulbs include:
1. Higher brightness: Improves nighttime driving visibility and safety.
2. Lower energy consumption: saves vehicle electrical loads.
3. Longer life: Reduces replacement frequency and maintenance costs.
4. Faster response: quicker illumination helps improve reaction time.
5. More modern appearance: Improve the overall aesthetics of the vehicle.
How much does it cost to convert headlights to LED?
The cost of converting headlights to LEDs usually depends on the model, brand, and quality of the LED headlights. The approximate cost range is about $30 to $200 per headlight, and the entire conversion process may include replacing bulbs, controllers, and circuits for an overall cost of roughly $50 to $300.
What is the average lifespan of a Chevrolet Cobalt LED headlight?
The average lifespan of a quality Chevrolet Cobalt-specific LED headlight is usually around 30,000 hours, which is more than 30 times that of a stock halogen bulb (about 1,000 hours). But the actual lifespan depends on the thermal design and brand quality. For example, RIMTHIN's LED bulbs have a better quality of life and can last up to 50,000 hours.
Will LED headlights be brighter than traditional bulbs?
Yes, LED headlamps are typically brighter than traditional halogen bulbs, have higher luminous efficacy (up to 6 times more than halogen), use less energy, and last longer.
Is it legal to replace headlights with LEDs in the US?
In the United States, the legality of replacing headlights with LED headlights depends on meeting the standards of the National Highway Traffic Safety Administration (NHTSA) and state traffic laws. If the replacement LEDs meet Federal Motor Vehicle Safety Standards (FMVSS 108) and are certified, they are generally legal.

H1 high beam replacement.
These bulbs did the job nicely, not too bright for my needs and they don't blind drivers. Installation was easy on a 2013 Elantra high beam replacement. Will update if anything changes in the long run.

Well worth the money
These LED lights are amazing!! I normally don't write reviews unless something really impresses me. My wife's SUV was blowing halogen bulbs every few weeks. I got tired of buying bulbs, replacing bulbs. (NO, I WAS NOT TOUCHING THE GLASS!) I bought here these for the longevity, but was blown away by how much they improved the visibility. I don't know how long these will last, but i know when my truck is due for bulbs, ones like these are going in it!! Behold the pictures, these are low beams. They even shine to the sides better, which in deer country, is an asset

Such an improvement.
I have a 2014 Prius C. Still had factory lights and could barely see. The color and brightness is perfect not to mention the great price. Way better deal here than at the car shops. Highly recommend

These make a big difference
I bought these for our little commuter car because we didn’t get much light out of the stock lights. Photo attached is during install. Left is the new, right is the old. Super easy to install, it’s just plug n play. HUGE difference, great for the price, I highly recommend

Amazing! Bright white light and easy Installation.
The lights were a simple plug and play and they work amazingly. You can hear the little fans running so that helps me from leaving them on. Used same for high and low beams on 87 Chevy Blazer. Make sure you change all your lights to LED.

Good LED for the price
I like the pattern of the low beam a lot! Very bright. I struggled with adjustment, because when I got the low beam where I wanted it, the high beam seemed too high. Also the high beam seems to loose the pattern and diffuse a bit. Overall, they are worth the price. I opted to put the low beam where I liked it and live with the high beam not being optimal. I actually went a little low on the low beam to limit blinding other drivers. They do seem a bit bright oncoming

Much brighter and whiter than stock headlights.
I installed these headlights for my dad for Christmas because it was getting harder for him to see at night. World of difference. The white light helps a lot more and the install process took about a half hour.
