Narrative:

Due to the overnight icing weather in ZZZ; the aircraft needed to be deiced prior to departure. After pushback and engine start; we taxied to spot for deicing. We had to wait about 25 minutes for deicing to start due to a shift change and for the deicing truck to be refilled. Type 1 fluid was used to deice the aircraft. After communicating with iceman that the aircraft was ready and configured for deicing; the deicing crew started deicing the aircraft. The deicing procedure appeared to be normal; and once we were told that the deicing was complete and that the aircraft was clean; we completed the deicing checklist and departed uneventfully. While boarding at our destination; the jumpseat rider informed us that there was ice on the wings near the spoiler area. Iceman was called out to deice the aircraft. While deicing the aircraft; iceman informed us that the tail was also covered with ice. After being told that the deicing was complete and that the aircraft was clean; we completed the deicing checklist and departed uneventfully. The area where the deicing took place had very little to no lighting available and may have caused the deicing crew difficulty seeing the clear ice on the aircraft. To prevent this from occurring again; there needs to be proper lighting from either ground equipment and/or lighting on the deicing truck. The flight crew can turn on exterior lights such as wing lights and logo lights (if installed) to help illuminate critical area to be deiced. When communicating with iceman; make sure the lights on the deicing truck work properly.

Title: A B737-700 was deiced with Type I fluid before leaving an overnight station at dawn. At the next station they were told ice still adhered to the wings near the spoiler and the horizontal stabilizer. The aircraft was deiced before departure.
