You should do it. But there are some things to check for:
1. Make sure there is enough room on the sides to hide the bulb. I have them on my car and there isn't much room to hide the bulb, it actually sticks out about halfway

. Yes, I put them in myself (me and some friends)but trust me, the only way to hide them on my car would be to get side skirts (which I am planning on getting someday). There is so little room under my car.
2. Are you willing to change your style of driving? You can't jump train tracks, go fast down dirt roads, and gotta watch out for curbs.
3. Do you want the po po on you? I don't know about the laws where you live but here you can't drive with them but they can be on in the parking lots. On more than one occasion, I have had cops pull up behind me in a parking lot and ask for my license, etc and try to convince me that they aren't legal at all.
All in all, I think they are a good investment and I love the attention my car gets because of them. Go for it.
