Ladies and Gentlemen:

This opinion is furnished to Neonode Inc., a Delaware corporation (the “Company”), in connection with the resale under the Securities Act of 1933, as amended (the “Securities Act”), of 5,027,352 shares of the Company’s common stock, par value $0.001 per share, that are issued and outstanding (the “Shares”) and up to 7,913,676 shares of the Company’s common stock, par value $0.001 per share, (the “Warrant Shares”) that are issuable upon exercise of outstanding warrants (the “Warrants”), pursuant to the Registration Statement on Form S-3 (the “Registration Statement”) filed on September 2, 2016 with the Securities and Exchange Commission (the “Commission”) and the related prospectus included therein (the “Prospectus”).

As counsel to the Company, we are familiar with the proceedings taken and proposed to be taken by the Company in connection with the issuance and sale of the Shares and the Warrant Shares. We have examined the Registration Statement, the Warrants, the Company’s Amended and Restated Certificate of Incorporation, the Company’s Bylaws, certain resolutions of the Company’s Board of Directors, and other proceedings of the Company related thereto. We have also examined such records, documents, and certificates of public officials and of the Company, made such inquiries of officers of the Company and public officials, and considered such questions of law as we have deemed necessary for the purpose of rendering the opinions set forth herein.

Based upon the foregoing, we are of the opinion that (i) the Shares have been duly authorized, validly issued, and are fully paid and nonassessable, and (ii) the Warrant Shares have been duly authorized and, when issued and delivered by the Company upon exercise of the Warrants and payment of the exercise price in accordance with their terms, will be validly issued, fully paid and nonassessable.

We do not express or purport to express any opinions with respect to laws other than the Federal laws of the United States of America and the General Corporation Law of the State of Delaware, including the applicable provisions of the Delaware Constitution and reported judicial decisions interpreting such law.

We consent to the use of this opinion as an exhibit to the Registration Statement and further consent to all references to us under the caption “Legal Matters” in the prospectus constituting a part thereof and any amendments thereto. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.

Very truly yours,
