The story
Trang is already running; Roi Et opens on 9 October with a longer listed evening window. Your dates and Trang's unresolved start time shape the choice.
October 4, 2026
Two regional evenings with different dates
Should a traveler choose Trang now or wait for Roi Et? On 4 October, Trang is the immediate VIJIT Thailand option, while Roi Et starts later. Lamphun's official programme ends on 4 October, so it is excluded from the forward-looking choice. Start with the event that fits your existing itinerary.
The Tourism Authority of Thailand programme release lists Trang for 2–11 October and Roi Et for 9–18 October. Their dates overlap on 9–11 October, but the checked official material establishes no practical inter-city route or transfer time. These are separate regional evening choices, with no verified basis for calling them a convenient combined trip.
Trang is available now, with a start-time caveat
“Trang Lights Alive” takes place at Chaloem Phrakiat 95 Public Park in Mueang Trang. TAT describes 10 illuminated experiences around the lakeside park, including Magic Island and dugong, forest and multicultural themes. This is the announced programme, rather than a firsthand account of the installations or visitor experience.
The official hours conflict. The central TAT release says 17:00–22:00; the TAT Event Data Center's Trang listing says 19:00–22:00. Both list a 22:00 close, but the two-hour difference in opening time remains unresolved. Confirm the current start with the local organiser or TAT Contact Center 1672 before arranging your arrival.

Trang is a reasonable immediate option if your southern travel plans bring you to the area before 11 October. Its opening-time uncertainty matters when fitting the event around another commitment. The research does not establish a walking duration, easy access or a quiet visit, so leave those expectations open.
Roi Et has later dates and listed entertainment
Roi Et runs at Bueng Phlan Chai from 9–18 October. The central release, TAT October calendar and Roi Et event page agree on 17:00–00:00. That is the longer stated nightly window, although it does not tell you how much time a visit requires.
TAT lists 10 installations using illumination, mapping, lasers, mist, LED and sound. Opening-night fireworks are scheduled for 19:30 on 9 October, with live music listed for 9–11 and 17–18 October. Those dates make Roi Et the clearer schedule match if a fireworks or music evening is your priority. They are official programme listings, subject to change, rather than observed performance reports.
Choose by itinerary, then confirm the gaps
Choose Trang for an evening available now if it fits your southern stop and you can confirm the opening time. Consider Roi Et if your dates fall from 9 October onward and its longer listed window or dated entertainment is useful. Neither is a universal winner on convenience, value or atmosphere from the evidence available.
Costs remain unverified: the checked sources establish neither an admission price nor a free-entry rule. Registration requirements, parking, accessibility, road controls and last-mile travel times are also unresolved. Recheck both event pages and confirm the details that affect your visit before committing to transport or accommodation. The research draws on official programme information; it contains no independently verified pattern of queues, crowding, visitor satisfaction or resident response.
