Q: What does S-MOD stand for?
A: It is our Signal® Mirror on Demand™ kit. This kit is a retrofit specific kit which is built just for you when you place your order. This manufacturing flexibility give us the ability to offer applications for most vehicles.

Q: What is the lead-time?
A: Unlike our production based retrofit specific kits, these can take up to 14 days (10 business days) to process.

Q: I see a mirror size listed; how do I compare to my mirror?
A: You will need to measure your mirror from the lower outboard side to the upper inboard side for each mirror on your vehicle. If there are multiple sizes listed, selecting the correct size is critical to assure a proper fit. If you only see one size, it’s likely your vehicle only has one mirror available from the factory. (It doesn’t hurt to measure if you’re not sure.)

Q: I don’t see an answer to my question. How can I contact Muth Mirror Systems?
A: Go to our Contact Us page to see all of the ways to contact us!

Q: What type of warranty comes with the Signal Mirror® kit?
A: The Signal® mirror is warranted to be free from defects in materials and workmanship for a period of 3 years from date of sale to original purchaser. This warranty excludes labor, broken glass, or other situations that cause harm to the product after it has been shipped from the factory–such as damage, unreasonable use, modifications, or alterations. In the event of a defect, Muth reserves the right to evaluate the problem through Quality Control and at Muth’s discretion, replace the defective product. Any warranty replacement part will be charged to the customer when shipped. Credit will be given when the defective part is returned to and received by Muth, and the replacement is warranted.

If you have an open account, a credit will be issued against your account. Warranty covers replacement cost of product only.

Q: What is the return policy?
A: Since the mirrors are built specifically for you when you order, requiring ordering of specific components for your vehicle, returns are not available for the S-MOD™ kits. Please be sure you want Signal® Mirrors before you place your order.

Q: I already have Signal® mirrors! What is the best way to care for them?
A: The best way to keep your Signal® mirrors looking brand new is to use a glass cleaner and a soft cloth. If you are cleaning the painted or chromed surfaces of your mirror housings, use a proper cleaner.

Q: Are Signal® mirrors street legal?
A: Yes. As a matter of fact, many sheriff and police departments use and enjoy the additional safety provided by Signal Mirror® technology.

Q: How are the LEDs in the Signal® mirror powered?
A: Power for the LEDs in Signal® mirrors are supplied from the left and right turn signal circuit in your vehicle.

Q: What if I have EC (electrochromic or self-dimming) mirrors?
A: An S-MOD kit may still be available for your application, but you will lose the EC feature. Please contact a Muth representative for more details about your specific application.
