Patlite signal towers are available in 25mm, 30mm, 40mm and 70mm diameter sizes and offer high intensity LED illumination and prism-cut lens design for enhanced visibility from any direction. Ideal for tight spaces, the 25mm ME/MES series of super slim rust-free aluminum body signal towers is available in one to four LED module versions. With an ABS resin main body, 30mm MP/MPS series and 40mm LCE series signal towers offer superior impact and heat resistance. Models are available with built-in or add-on alarm buzzers. 70mm LS7 series towers have a smooth body that reduces adhesion of water and dust, making these signal towers adaptable in many environments including high pressure and high temperature wash down. Pre-assembled Patlite stack lights start at $79.00. Replacement LED modules and mounting brackets/poles accessories are available.
