Our simple, fast "plug and play" installation can be done by just about anyone. Our wide varieties of LED bulbs are compatible with most makes and models, including some after-market vehicles.
Switchback turn signal bulbs are designed for dual filament sockets. When you are driving and using your running lights, the lights will shine bright white. If you use your turn signal, the bulb color switches to bright amber. Once you're done with the turn signal, the color will "switch back" to the bright white filament.
The 3157 LED bulb is the dual filament option for the 3156 LED bulb. You can easily use a 3157 bulb with a 3156 socket. The two will work together seamlessly to, instantly upgrade and update your older, dimmer Halogen bulbs with the unmatched brightness of an LED Turn Signal. Note: A 3156 bulb can't work in a 3157 Socket.

I entered the information for my vehicle into your website and it told me which bulb to order. I receive the wrong bulb and your answer was immediately to tell me that I messed up and ordered the wrong item. I realized I did mess up by choosing the wrong company to do business with, so I stuck it up and pay for shipping to send your merchandise back. Then you want to further screw me over and steal $30 from me and act like it’s my fault again. And you wonder why Amazon is edging everyone out of business. You are the reason. You should have named your company Underhanded Lighting.

Contacted them today about getting my fog light bulbs replaced. What I hate about buying stuff like this online is waiting for it to show up, only to have it not fit. I loved dealing with them because I could CALL and talk to someone right away that knows what my truck would need, instead of me ordering the wrong one on my own. I dialed them up, told the guy exactly what I wanted- he looked up the part, and processed my order right away. It took less than 5 minutes, and I’m confident it’ll be right the first time.

Came to Underground lighting for my Nissan 350z. The headlights weren’t working and in all honestly seemed to be an impossible job. But with in 2 hours he diagnosed the issues and fixed the issues I had. Now my headlights are working perfectly. Supper friendly owner willing to work with you, I couldn’t recommend him enough!

I had to replace my headlights on Hyundai Genesis coupe and I could not find one available that fit my old kit. Danny took care of my issue by replacing the whole kit. He was available to fix on last minute notice and finished it in an hour. It’s also kinda nice to have a 1 year warranty with his kit installation. Thanks Danny!

Great service. I had issues with my leds not being installed right by another company. Danny went right to work and began rewiring everything correctly. Danny took his time and made sure everything was correct and in proper order. 10/10 would recommended to anyone. Danny’s knowledge and workmanship alone make me recommend him and his company to anyone looking to install the smallest things to complete projects.

Danny has always provided me with great service whether it was answering my calls or sending me the parts I needed quickly. Overall I finally took my truck that had problems for over a year with the HIDs to him, and within an hour he swapped them to high quality LED's which I am very happy with! Great products and great service. And if your unsure about the price, you get what you pay for, pay more for the quality! It's worth it!

We were looking to change out the yellow factory lights on our car which was recently purchased. We asked the dealership if they could do it and they recommended a local shop.Went to the shop who installed aftermarket headlights and fog lights. The color was fine but the lights just didn't light up the road. As a matter of fact they were worse than the factory ones as far as brightness goes. After being so disappointed, and doing some more research, we came across Underground Lighting after doing several google searches. Went and met Danny who was very professional and explained all about the aftermarket
