Product Information
The Bigblue TDH-04 Helmet Light Mount is a helmet-mounted light mount that attaches a dive light to a diving helmet, and it fits all lights featuring the Bigblue Mounting Square on the light head. It is sold as the mount only: the helmet and the lights are not included.
Who it is for
This mount is for divers who want hands-free lighting on a helmet instead of carrying a light or running a goodman handle. It suits technical and recreational divers building a helmet-mounted setup, including the dual-light dive helmet configurations Bigblue shows with this accessory, and anyone who already owns a Bigblue light head with the Mounting Square interface and wants to move that same light onto a helmet. Because it is a single-purpose adapter, it is also a sensible spare for divers who run more than one helmet or who swap light heads between mounts.
Key details
- Model: Bigblue TDH-04, listed by Bigblue as the Technical Diving Helmet Light Mount.
- Interface: the Bigblue Mounting Square found on the light head, including Bigblue 3000-series heads.
- Scope of supply: mounting bracket only, no helmet and no light.
Compatibility and sizing
Any Bigblue dive light that features the Bigblue Mounting Square attachment system on the light head will fit the TDH-04. If your light head does not have the Mounting Square, this mount is not the correct adapter. Bigblue shows the TDH-04 alongside its dual-light dive helmet products, such as the VTL4200P, so check your own light head for the square interface before ordering.

Frequently Asked Questions
Which lights fit the Bigblue TDH-04 helmet mount?
The TDH-04 fits all lights featuring the Bigblue Mounting Square on the light head, which includes Bigblue 3000-series heads. If your light head has that square attachment interface, it will mate with this mount. If it does not have the Mounting Square, the TDH-04 is not the correct adapter for it. Bigblue also shows the TDH-04 with its dual-light dive helmet products, such as the VTL4200P.
Does the TDH-04 include a helmet or a dive light?
No. The TDH-04 is sold as the mount only. Bigblue lists the box contents as the Technical Diving Helmet Light Mount, TDH-3000 Light Mount, and states that the helmet and the lights are sold separately. You supply your own diving helmet and your own Bigblue light head with the Mounting Square interface to complete the setup.
Can I run two lights on a helmet with the TDH-04?
Bigblue shows the TDH-04 alongside its dual-light dive helmet products, such as the VTL4200P. Call 888-701-4017 and we will review your helmet and light heads. Contact us at 888-701-4017 and we can go over your helmet and light heads with you.
Is the TDH-04 the same thing as the TDH-3000 light mount?
Yes. Bigblue sells this accessory under the model number TDH-04 and names it the Technical Diving Helmet Light Mount, while the published box contents read Technical Diving Helmet Light Mount, TDH-3000 Light Mount. Both names refer to the same helmet-mounted bracket that accepts lights with the Bigblue Mounting Square.
