the circuitry inside the suppressor that handles a surge can burn out if a surge is too high or lasts too long; in which case the cord would continue to work without surge protection making the connection vulnerable.
So it will indicate the device is protecting equipment.

A surge limiter (or surge suppressor) can be installed into your electrical panel to help protect your home from dangerous electrical spikes. It is usually installed in conjunction with a lighting arrestor. You can also buy single use surge protectors for sensitive appliances, such as computers, tv's, and stereo systems.
It can, if the light is a capacitance type of lamp that you touch to switch it on, then a surge can turn it on.
When the power applied to a surge suppressor goes above the rated amount, a certain amount of that power diverted down a ground wire and dissipated. Surge suppressors wear out and should be replaced every two years. Answer: Any suppressor that degrades or 'wears out' in two or ten years is grossly undersized, is ineffective protection, and may even create a fire. Suppressors must be properly sized to not fail. For AC mains, a suppressor must connect short to earth (be adjacent) to what actually absorbs energy). Suppressors that make an effective (short) connection to earth are also rated at least 50,000 amps. To not fail even on direct lightning strikes. An effective suppressor connects transients (even tens of thousands of amps) to what harmlessly absorbs that energy: earth ground. A completely different suppressor adjacent to an appliance must somehow block or absorb that energy. These hundreds joule devices require frequent replacement when absorbing destructive surges that exceed tens of thousands of joules. Suppressors that need frequent replacement are undersized and are typically too far (many tens of feet) from earth. Completely different devices, called suppressors, last for decades and are located adjacent to earthing electrodes.
Destructive surges can be hundreds of thousands of joules. A protector rated for hundreds of joules does not claim to protect from the other and typically destructive surge. In fact, a 250 joule surge will simply be converted by electronics into low voltage DC to safely power its semiconductors. A destructive surge may be 20,000 amps. So a minimal 'whole house' protector for all homes should be at least 50,000 amps. Any protector that fails on a surge did not provide effective protection. And was a potential house fire.
Answer Most of the surge suppressor indicator lights only show if the power is present and turned on. It does not add any other functionality in terms of surge suppression. Only if a particular model indicator shows that there was a surge on power line, it makes it more useful for the user as person can investigate reason or surge if it is happening repeatedly. Iindicator should be clearable manually by user. - Neeraj Sharma "...it's important a surge supressor has a light indicator that says the supressor part of the device is still working. Otherwise, you might not have protection" A+ Guide to Managing & Maintaining your PC (page 161) -MonkGizmo That indicator light cannot report all failures. Normal failure mode for a protector is to degrade. That light cannot report a degraded protector. That light only reports that a surge, much too large for the protector, caused its thermal fuse to disconnect protector parts as fast as possible. To avert a fire. That light can only report a type of failure that says a protector was grossly undersized. And a potential threat to human life if that fuse did not blow fast enough.

It really does vary as to how much a surge suppressor costs depending on where you buy it from. They usually range from $15 to $25. Here is one site you can buy them: www.tigerdirect.com/.../category_slc.asp?...Surge%20Suppressors

A surge suppressor. Better yet,an UPS (uninterpretable power supply) with a built in surge suppressor.
a surge suppressor or protector protects your equipment from spikes on the electrical line.
There is likely no difference. Neither is accepted terminology for a surge suppressive device (SPD). If these products have been tested by safety organizations such as CSA (Canada) or UL (US) or tested to international surge standards (IEEE, IEC), then they should bare the correct terminology, otherwise, they are not tested to provide protection to equipment during a surge. Surge Absorber acts as a load that utilizes the high current until it exhausts. but the surge suppressor diverts the high current into ground without reaching the sensitive parts of the circuit. Surge absorber degrades faster than a surge suppressor.
Surge suppressor
A surge suppressor or protector is used to protect electronic devices in case of voltage spikes. A surge protector works by limiting the amount of voltage supplied to the plugged in electronic devices by blocking or shorting to ground any voltage above the safe threshold.
A surge protector, also called a surge suppressor.
