The power light lights up when I plug it in, but the OBD light doesn't light up. At what point does the OBD light shine when it actually works?

Honestly I don't know because I use Torque on my Android & read the PCM displays there, never looking at the Excelvan. Besides that.....My OBD port is inverted so the Excelvan is facing down so I can't see the lights.

The ABS light should always come on when first starting the car as it goes through its system check, then go out. My ABS would activate when coming to a stop, but my light never came on. After much trial and error and expense, I finally took it to the dealer. The sensor would not send the correct signal at slow speeds so the ABS thought that wheel was locking and activated. Save yourself some time and money and have someone with a scan tool check the sensors while driving. It will show the outputs of each sensor at different speeds and indicate a faulty one. If you need one, Amazon has the best price. The ABS light should always come on when first starting the car as it goes through its system check, then go out.

Jose, return it for a new one. That is exactly what happened to me. The second light works great! I have a chev silverado and I put the light under the license plate in front. Looks and works great!

I had a similar problem. I called it ground feedback. No one else heard of it. When I put these in I get a faint glow on the dash turn signal indicators and the front turn signal lamps are also glowing slightly. This was with a pair of cheap knock off lamps installed. I am going to try the JDM Lamps to see if better quality makes any difference.

Black goes to black, or ground. For the other 2 wired one is the running light and one is the brake light. Hook up both wires and test the brakes. It should light up, and light brighter when u hit the brakes. If its not working right, flip flop the wires

It is just the lights.... I don't have a focus, so you have to check if the car is pre-wired for the lights.

On my tester, it will either light up or not, might be a loose connector be sure and check the leads into the the plastic 20pin connector, that they are all seated and the female connectors are not spread out..

without actually being there, my guess is you have weak tie in connections. Since you have indicated that it does work but intermittently, it appears to be a bad connection. The wires that come with the unit are very thin and need more surface contact area and the connection wires need to be shiny when mated to your vehicle wires which should also be bright. Fool proof way is to solder but that is difficult with the small gauge wires.

Have you considered that it may be just broken ? It should light up right when you plug it in. Play with the sensitivity ... If still nothing them obviously it's broken.

Hi Bret, I have not got mine yet but being in the automotive field for over 30 years I would say it will draw next to nothing to run that tester it should light red or green led but it would take any power to do that I will let you know when I get it for sure

Mine did the same thing, I removed the capacitor (round black cylinder on the back) and it works perfect now, steady and bright.

Paula,I've tested this and though the power LED lights up, it will not convert the signal properly. You will need to find a separate part for that.

Well I had no problem mine is working very well, I suggest you to check your car for any fuse or electric problem or try it in another car's lighter to be sure what's the problem you have

If it is the same as mine, the light is only on when it is providing charge to the car. It is not on all the time.

what year vehicle do you have? When you turn on the Halo's the driving lamps should light up also.

We installed the new battery and when we started pedaling the display came on. If you've tried pedaling and it didn't light up, I'd start by checking to see that the voltage at the battery is good and if it is, there may be another problem.
