Re: Sale of Common Stock pursuant to Registration Statement on Form S-3

Ladies and Gentlemen:

This opinion is furnished to you in connection with a Registration Statement on Form S-3 (Registration No. 333-219596, the “Registration Statement”), the prospectus included therein and the related prospectus supplement (such prospectus, as supplemented by such prospectus supplement, the “Prospectus Supplement”) filed or to be filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the sale of 555,556 shares of your common stock (the “Shares”).

We are acting as counsel for Micronet Enertec Technologies, Inc. (the “Company”) in connection with the registration and sale of the Shares. We have examined copies of the Registration Statement and Prospectus Supplement filed or to be filed with the Commission. We have also examined and relied upon minutes of meetings of the Board of Directors of the Company as provided to us by the Company, the Certificate of Incorporation and By-Laws of the Company, each as restated and/or amended to date, and such other documents as we have deemed necessary for purposes of rendering the opinions hereinafter set forth.

In our examination of the foregoing documents, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, the authenticity of the originals of such latter documents and the legal competence of all signatories to such documents.

For purposes of our opinion, we have examined the General Corporation Law of Delaware. Other than such examination and our examination of the documents indicated above, we have made no other examination in connection with this opinion. We express no opinion herein concerning the federal laws of the United States of America or any state securities or blue sky laws. We assume that the appropriate action will be taken, prior to the offer and sale of the Shares, to register and qualify the Shares for sale under all applicable state securities or “blue sky” laws.

Based upon and subject to the foregoing, we are of the opinion that the Shares, when issued as contemplated by the Prospectus Supplement, including the receipt by the Company of the consideration therefor will be duly authorized, validly issued, fully paid and non-assessable securities of the Company.

Please note that we are opining only as to the matters expressly set forth herein, and no opinion should be inferred as to any other matters. This opinion is based upon currently existing statutes, rules, regulations and judicial decisions, as further limited above, and we disclaim any obligation to advise you of any change in any of these sources of law or subsequent legal or factual developments which might affect any matters or opinions set forth herein.
