The 37th (Tyne Electrical Engineers) Searchlight Regiment, Royal Artillery was an air defence unit of Britain's Territorial Army (TA) during World War II.

During World War I the TEE had been the parent unit for almost half the anti-aircraft (AA) searchlight companies formed for service both at home and overseas.

[8] When the TA doubled in size following the Munich Crisis, the TEE formed a duplicate unit as a Light Anti-Aircraft (LAA) regiment of the Royal Artillery (RA), designated 37th (Tyne Electrical Engineers) LAA Regiment, RA (TA), which and was still in course of formation at Tynemouth when World War II broke out in September 1939.

[12][13] By early 1940 the regiment was at Bordon Camp, and at the beginning of May moved to Aldershot to prepare to join the British Expeditionary Force (BEF) in France.

The Composite Battery and 307 Battery eventually joined RHQ, driving through streams of refugees, but because of the rapid advance of the Germans, they were withdrawn to take up positions protecting Le Havre (307 Bty with 24 lights) and Harfleur (Composite Bty with 13 lights), under 3 AA Bde while the main BEF was being evacuated from Dunkirk.

By now Le Havre was under continuous bombing attacks, and 307 Bty provided a detachment with light machine-guns and anti-tank rifles to reinforce the land defences .

RHQ remained at Tewkesbury until September 1942 (with the exception of training camps at Rhyl and Briton Ferry in August–September 1941), with the batteries deployed as follows:[28][29] On 27 July 1942 the lights of 37 Regiment were engaged during a raid on Cheltenham (part of the 'Baedeker Blitz').

Air raids were becoming uncommon, and with the lower threat of attack by the weakened Luftwaffe, AA Command was being forced to release manpower for Overlord, and all Home Defence searchlight regiments were reduced by a battery.

Troops of 37 S/L Regiment were deployed to the Essex and Suffolk coast to support the brigades of AA guns engaging the V-1s.

After VE Day the regiment moved to Widnes, but 308 Bty remained in Norfolk conducting War Office trials.

[34][35][36] When the TA was reconstituted on 1 January 1947, 37th (TEE) S/L Rgt with its three remaining batteries (307, 308, 348) was placed in suspended animation at the Militia Camp, Royston, Hertfordshire.
