10. SIGNIFICANT CUSTOMERS AND CONCENTRATION OF CREDIT RISK

Royalty income from Econolite comprised 56%, 56% and 58% of revenue in the years ended December 31, 2015, 2014 and 2013, respectively. Accounts receivable from Econolite were $1.4 million and $1.5 million at December 31, 2015 and 2014, respectively. Major disruptions in the manufacturing and distribution of our products by Econolite or the inability of Econolite to make payments on its accounts receivable with us could have a material adverse effect on our business, financial condition and results of operations. Econolite was the only customer that comprised more than 10% of accounts receivable as of December 31, 2015.
