Narrative:

After takeoff the first officer retracted the landing gear after the positive rate gear up call was made. The landing gear lights (both red and green) were illuminated on the center forward panel. We elected to stay in close proximity to [departure airport] and troubleshoot the problem. The captain was pilot flying and the first officer (first officer) ran the checklist for gear disagree.we requested holding and completed the checklist while in the holding pattern. After the completion of the checklist we determined that the gear remained in the down and locked position. The overhead landing gear indicator lights were all illuminated green.at 6;000 feet in the holding pattern - we attempted to contact arinc; but due to the low altitude communications were difficult to establish with dispatch and [maintenance]. We climbed to 11;000 feet and reestablished contact with [maintenance] and dispatch. We discussed the situation with [maintenance] and followed guidance to check the floor plate door for the alternate gear extension. The door was properly seated and closed. Maintenance advised us to attempt a retraction of the gear and we both discussed the situation and elected to leave the gear in the down and locked position. Furthermore; we burned up close to 4;000 pounds of fuel and could not continue to [destination] without a fuel stop along the route. Additionally; we notified dispatch that we were going to return to [departure airport] with an overweight landing aircraft. We advised dispatch of the overweight condition and obtained performance for our takeoff weight of 154.0 and actual landing weight of 148.0. At [flaps 30] our performance was acceptable for [the planned runway]. ATC vectored us out of the holding pattern for an ILS. An uneventful landing was achieved followed by a termination checklist at the gate. Maintenance was alerted to the two write ups dealing with the gear disagree lights and the overweight landing.
