An EUV light source having a simple structure which is capable of generating EUV stably with a sufficient intensity and serves as an alternative to a laser plasma light source. A camera captures images around the vehicle. When the programmable processor and the executable control software detect the first condition, the transceiver can exit the low power sleep mode and the programmable processor and the executable software can construct and transmit a message, via the transceiver, to a remote device. During dim or poor light condition, the recharged battery provides electricity to the LED light bulb in a shower stall environment.
