check the radiator. ;)
just happen to me today the flashing battery light means your alternator is going bad and it is draining your battery..so your car may crank a few minutes before, but may put you down while you're out and about so be careful where you drive, because your battery can lose power in less than a minute of driving because of the alternator..car will stall instantly.
your alternator is bad even if you charge your battery it could still die because the battery is being wasted while you drive

The flashing blue lights on the wiimote means the wiimote is sending a signal to find and synchronize with a local Wii console. Whenever the wiimote does not find a powered-on wii console that it is synchronized to, the wiimote will only flash blue lights for a short time. Only when the wiimote connects to a Wii console will the flashing stop and keep one light on to indicate what player the wiimote is controlling. Furthermore the flashing lights also indicate how much battery life remains. Four flashing lights indicates full battery life while one flashing light means very low battery life.
You can drive the car but should have the vehicle checked soon as possible. BUT if the service engine soon light is flashing, stop the vehicle when it is safe to do so then shut off the engine immediately. If you continue to drive the vehicle with the service engine soon light flashing you will do catastrophic damage to the catalytic converter(s).
Call the company that produces your detector an ask them. Other wise try your local fire department. Some detectors always flash to let you know that they're on and functioning properly. Although, it could be broken or low on battery power.
I'm not positive about your car, or the dash setup, but generally a water light means your low on coolant. If you drive while low on coolant, you run the risk of overheating your engine. Obviously that's not a good thing.
Replacing the battery should not have triggered the check engine light. The check engine light comes on when there is a problem with the emission system. Saying that, I would drive it for a while to see if the light does go out. If the light does not go out have the ECU scanned to retrieve the trouble code. Then use this code to diagnose the problem.
The battery has a temperature sensor. If it was left unplugged, the battery light will still be on
A flashing red traffic light is used the same way as a stop sign. You treat a flashing red traffic light the same way you do as a stop sign. If the traffic light is "blacked-out", it's to be treated as an all-way stop. What I do when I come up to a flashing red traffic light, I look at the cross-traffic signals to see if they're also flashing red, or if they're flashing yellow to see if they stop or if they don't stop.
I was just corrected on this myself. The short answer is no; however, the long answer is maybe: The real issue isn't the LED being LIT (as opposed to FLASHING). Some USB ports will cause the LED to light even when there is no activity; in which case, it is safe to remove the drive. However, if the LED is flashing, it is not safe to remove the drive.
Dead cell in the battery, or parasitic drain from a light that is on or a relay that is stuck.
