Lamp out alarm keeps sounding

Is it a small light somewhere on the dashboard? I'm not familiar with that car, but any vehicle I've had with an alarm has a blinking light to warn you/intruders that there is an alarm on the vehicle. Check your owner's manual for more info.

Normally, when one of your turn light blinks fast, means that the other is burned out ((i.e. the right forward blinks fast, right rear burned out)

How To Change Burned Out Turn Signal Light Bulb 2013 Ford Expedition

Here is what the service manual says. Looks like it is not a flasher relay but a function of the body control module.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEMSystem Description OUTLINE Turn signal lamp and the hazard warning lamp is controlled by combination switch reading function and the flasher control function of BCM.
TURN SIGNAL LAMP OPERATION - BCM detects the combination switch condition by the combination switch reading function. - BCM supplies voltage to the right (left) turn signal lamp circuit when the ignition switch is turned ON and the turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.
HAZARD WARNING LAMP OPERATION BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the hazard warning lamp.
TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION - BCM transmits the turn indicator signal to the combination meter with CAN communication while the turn signal lamp and the hazard warning lamp are operating. - Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal indicator lamp according to the turn indicator signal.
HIGH FLASHER OPERATION (FAIL-SAFE) - BCM detects the turn signal lamp circuit status by the terminal current value. - BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal lamp operating. NOTE: The blinking speed is normal while operating the hazard warning lamp.

warning lamp some used for warn low oil pressure, etc.
Wtith the bulbs use for most warning light circuit it is hard to determine whether or not the filamente is good. Will be a good idea to replace the bulb.
For test the faulty warning lamp, turn the ignition switch to START, this light the warning lamp. I f the light does not come on , disconnect the sender switch lead. . Use a jumper wier to connect the sender witch lead to ground. With the ignition in RUN the warning lamp should light. If the lamp is illuminated replace the sending switch. If the light does not come on,either the bulb is burned our or the wiring is damaged.Use test light for confirm voltage is present at the sensor terminal connector. If there the bulb is bad.
God bless you

You must have the dealer service dept scan the system to see what is causing the fault.

This will help.

Thanks.

sound as bad connection, inspect battery terminals and grounds, also inspect ignition switch connector for bad contact and burned out pins, if so need to replace switch and repair connector, did not stated what year or eng. size

you have a short circuit or burned out wires somewhere, could be anywhere.
Try disconnecting the alarm, taking the bulb out of the interior lights, and putting in the fuse, if it blows again you know that the alarm or interior lights are not at fault, if it stays good replace the bulb and if it blows theres your faulty circuit, if it stays good then the windows are at fault.

This is the security indicator light. Designed to alert potential theives that the alarm is active. It is a L.E.D. lamp, and will not drain the aux battery. Nothing to worry about, this is normal. Hope this helps, and Thanks for choosing FixYa!

This is the taillamp failure indicator. You either have a burned out taillamp or a burned out brake lamp bulb(s). Please make sure when you check for inoperative brake lamps that you make sure that the brake lamp in the rear window works, also.
