If you want the largest selection of automotive Compass Bulbs & HID you have come to the right place! We have so many different colors to choose from you might get over whelmed. We have bulbs ranging from near blue color all the way to white and yellow. Purple is also a nice exotic color. Our colored bulbs are mainly designed for off road use, as none are DOT certified. However, in most states you should not have a problem. We personally have used these Compass Bulbs & HID in our own vehicles for years without any concerns. The sizes of bulbs are many, and you need to use our bulb application guide to figure out what bulbs you need. Our bulb application guide is on each of our bulbs pages. Simply click on it and you will be sent to a website which you can choose your make/model and find what bulbs fit your car.
