I have a question related to the red light on the bottom of the radio that has the words "Anti-Theft" written next to the red light. It blinks like it is suppose to when the engine is off. However, the red light remains on but does not blink when I am driving vehicle. Does it work the same way in your 99 Honda Accord Ex? In other words, in your honda--does the red light on the bottom of the radio remain on or off while you are driving the vehicle. When I posted the above question, one person told me that the red light mentioned above was not on while he was driving his 99 Honda Accord EX. My new questions: What causes it to remain on while I am driving my vehicle and how can I fix this problem?
